| CVE-2026-89477 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: sctp: fix NULL deref on untransmitted RECONF completion sctp_process_strreset_outreq(), sctp_process_strreset_addstrm_out() and sctp_process_strreset_resp() complete a pending stream reconfiguration request by stopping the reconf timer on the transport it was sent on: t = asoc->strreset_chunk->transport; if (timer_delete(&t->reconf_timer)) sctp_transport_put(t); chunk->transport is assigned by __sctp_packet_append_chunk() when the chunk is appended to an outbound packet, and sctp_outq_flush_ctrl() arms the reconf timer at that same point. A request already published in asoc->strreset_chunk but not yet transmitted has neither, so completing it dereferences NULL. Two ways to get there. sctp_send_asconf_del_ip() sets asoc->src_out_of_asoc_ok without sending anything when the address being removed is the association's last one, and sctp_outq_flush_ctrl() then leaves every non-ASCONF control chunk queued; as only sctp_process_asconf_ack() clears that flag, it persists. An unprivileged process that removes such an address and then asks for a stream reset panics the kernel from softirq. A peer needs neither ASCONF nor local help: sctp_cmd_interpreter() uncorks the outqueue only once the whole packet has been processed, so a reply built while walking a RECONF chunk stays untransmitted for the rest of that walk, and one RECONF chunk carrying [Incoming SSN Reset Request, Outgoing SSN Reset Request, Response] -- or two RECONF chunks in one packet -- reaches the same dereference. KASAN: null-ptr-deref in range [0x00000000000001e8-0x00000000000001ef] RIP: 0010:timer_delete+0x67/0x110 Call Trace: <IRQ> sctp_process_strreset_addstrm_out (net/sctp/stream.c:832) sctp_sf_do_reconf (net/sctp/sm_statefuns.c:4212) sctp_do_sm (net/sctp/sm_sideeffect.c:1172) sctp_assoc_bh_rcv (net/sctp/associola.c:1044) sctp_rcv (net/sctp/input.c:243) ip_local_deliver (net/ipv4/ip_input.c:262) process_backlog (net/core/dev.c:6680) </IRQ> A response can only acknowledge a request that was actually sent, so do not match asoc->strreset_chunk while chunk->transport is NULL.

| CVE-2026-89476 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 7.5 High |
| In the Linux kernel, the following vulnerability has been resolved: sctp: fix stream->outcnt underflow on duplicate RECONF responses A cached RECONF chunk may contain more than one request parameter. A duplicate response can therefore find and process the same ADD_OUT request again while another parameter is still outstanding, rolling back outcnt twice and possibly underflowing it. Track outstanding request types as bits and clear each bit after its first response. Later responses for the same request are then ignored. | ||||
| CVE-2026-89475 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 5.2 Medium |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: bq24257: fix use-after-free on remove The STAT-pin interrupt is devm-managed, so it stays armed until the devm cleanup that runs after remove() returns. remove() cancels bq->iilimit_setup_work while the threaded handler can still fire; that handler reschedules the work and dereferences bq, so the work runs against freed memory once devm frees bq. Make the delayed work device-managed with devm_delayed_work_autocancel(), registered before the interrupt request. The devm cleanup then releases the interrupt first, so the handler can no longer reschedule the work, and cancels the work before bq is freed. The explicit cancel_delayed_work_sync() in remove() is no longer needed and is dropped. Found by static analysis. | ||||
| CVE-2026-90713 | 1 Vllm-project | 1 Vllm | 2026-09-14 | 3.3 Low |

The manipulation results in denial of service. The attack is only possible with local access. The exploit has been released to the public and may be used for attacks. The pull request to fix this issue awaits acceptance. | ||||
| CVE-2026-89474 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 4.4 Medium |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: bq256xx: drain usb_work before freeing the charger The USB-PHY notifier queues usb_work, whose handler calls power_supply_changed(bq->charger). The reset devm action only unregisters the notifier and was registered before the power supplies, so devm frees bq->charger on unwind before the action runs; a usb_work still queued can then dereference it. Register the reset action after the power supplies, so it unregisters the notifiers and drains usb_work before the supplies are released. Initialize usb_work and obtain the PHY references before registering the notifiers, so the worker cannot run before the supplies exist. Found by static analysis. | ||||
| CVE-2026-89473 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 4.4 Medium |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: bq25890: Fix power_supply reference leak bq25890_fw_probe() acquires a reference to a secondary charger using power_supply_get_by_name(), but the reference is not released on later probe failures or on driver detach. In particular, failures after bq25890_fw_probe() returns successfully, such as a failure in bq25890_hw_init(), also leak the reference. Register a device-managed cleanup action immediately after acquiring the secondary charger. This releases the reference on all subsequent probe failures and on driver detach. Found by code review. | ||||
| CVE-2026-89471 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: cros_usbpd-charger: bound the EC-reported port count cros_usbpd_charger_probe() reads two port counts from the EC and uses one of them, num_charger_ports, as the loop bound when populating a fixed-size array: struct port_data *ports[EC_USB_PD_MAX_PORTS]; /* 8 entries */ ... for (i = 0; i < charger->num_charger_ports; i++) charger->ports[charger->num_registered_psy++] = port; Both num_usbpd_ports (from EC_CMD_USB_PD_PORTS) and num_charger_ports (from EC_CMD_CHARGE_PORT_COUNT) are u8 values reported by the EC. The only validation is a sanity check that compares the two EC-reported values against each other: if (num_charger_ports < num_usbpd_ports || num_charger_ports > num_usbpd_ports + 1) return -EPROTO; It never checks either count against EC_USB_PD_MAX_PORTS, the size of the ports[] array. A malfunctioning, malicious or compromised EC that reports num_usbpd_ports == num_charger_ports == N for any N > 8 (for example both 255) passes this check, and the loop then writes N pointers into the 8-entry ports[] array embedded in the devm_kzalloc()'d charger_data, overflowing it by up to 255 - 8 = 247 entries (~1976 bytes): a slab out-of-bounds write. Reject a port count larger than the ports[] array can hold. | ||||
| CVE-2026-89470 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: cros_usbpd: Limit port counts to EC_USB_PD_MAX_PORTS Currently the cros_usbpd-charger driver probe iterates based on raw charger port count returned by the embedded controller. The only check is against the number of USB PD ports which the embedded controller also defines. A malicious embedded controller could return an inaccurate port count (up to 255) resulting in an out of bounds write and subsequent memory corruption. Update helper functions in cros_usbpd-charger to limit port counts to EC_USB_PD_MAX_PORTS. | ||||
| CVE-2026-89469 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: lp8727: fix use-after-free in lp8727_release_irq() lp8727_isr_func(), the threaded IRQ handler, is the only caller that arms pchg->work via schedule_delayed_work(). lp8727_release_irq() currently cancels the work before freeing the IRQ, so an IRQ delivered in between can re-arm the work through the threaded handler. After .remove returns the devm layer frees pchg while lp8727_delayed_func() may still run and dereference it. Free the IRQ first so the threaded handler is quiesced and can no longer queue work, then cancel the delayed work to drain the final generation. This issue was found by an in-house static analysis tool. | ||||
| CVE-2026-89466 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 7.7 High |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: qcom_battmgr: terminate the strings from firmware The qcom_battmgr_sc8280xp_strcpy() takes a Pascal-style string when the firmware sends one. Otherwise it copies all BATTMGR_STRING_LEN bytes and leaves the destination without a terminator. Those destinations are model_number, serial_number and oem_info, each BATTMGR_STRING_LEN and declared next to each other. They go out to user space as val->strval, which power_supply_format_property() prints with "%s", so a firmware string that fills the whole field makes that read run into the following members. Use strscpy() so the copy always terminates, the way the SM8350 path already does for the same field. | ||||
| CVE-2026-89465 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 8.4 High |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: rt9455: quiesce delayed work before teardown The threaded IRQ handler can queue pwr_rdy_work, max_charging_time_work and batt_presence_work. pwr_rdy_work and batt_presence_work can also queue max_charging_time_work, while batt_presence_work can requeue itself. rt9455_remove() cancels max_charging_time_work before batt_presence_work. The latter can therefore queue max_charging_time_work after it has already been cancelled: rt9455_remove() workqueue cancel pwr_rdy_work cancel max_charging_time_work batt_presence_work queues max_charging_time_work cancel batt_presence_work return devres frees rt9455_info max_charging_time_work dereferences rt9455_info The IRQ also remains registered until devres cleanup and can queue more work after any of the cancellation calls. If rt9455_hw_init() fails after the IRQ has been requested, probe returns without cancelling work that may already have been queued. A pending callback can then access rt9455_info after it has been freed. Register rt9455_cancel_all_delayed_works() through devm_add_action_or_reset() right after devm_power_supply_register(). devres invokes the action in reverse registration order, after the managed IRQ has been freed and before rt9455_info is released, so the delayed works are drained in both rt9455_remove() and the probe error path. Cancel pwr_rdy_work and batt_presence_work before max_charging_time_work because both can queue the latter. This issue was found by an in-house static analysis tool. | ||||
| CVE-2026-89464 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 4.4 Medium |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: twl4030_charger: cancel workers via devm bci is devm-allocated. Two workers (bci->work and bci->current_worker) dereference it. twl4030_bci_remove() disables charging and masks interrupts. It cancels neither worker. A worker pending at remove() can run after devm frees bci. The USB transceiver comes from devm_usb_get_phy_by_node(). devm unregisters its notifier only after remove() returns. A cancel_work_sync() in remove() can then race a notifier reschedule. devm_work_autocancel() and devm_delayed_work_autocancel() avoid that. They cancel the workers during devm release, before bci is freed. The current_worker is registered first, since devm will cancel in reverse order and bci->work can reschedule current_worker.

| CVE-2026-89463 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 5.7 Medium |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: ucs1002: fix use-after-free on remove ucs1002 has no remove callback, so unbind runs entirely through devm. The alert IRQ handler queues the health_poll delayed work, and the work reschedules itself while the chip reports a bad-health condition. devm frees the alert IRQ, which only synchronizes the handler; it does not cancel the delayed work, which can then run after devm frees the driver data and dereference it. Register health_poll with devm_delayed_work_autocancel() before the alert IRQ is requested. devm then frees the IRQ before cancelling the work, so the handler can no longer queue it and the work is cancelled before the driver data is freed. This issue was found by an in-house static analysis tool. | ||||
| CVE-2026-89461 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: power: supply: max17040: synchronize work cancellation on suspend max17040_work() requeues itself after every poll. cancel_delayed_work() only cancels a pending instance and does not wait for a callback that is already running. If system suspend races with the polling callback, the callback can continue accessing the fuel gauge and requeue itself after the suspend callback returns. Use cancel_delayed_work_sync() to ensure polling is quiesced before suspend completes. | ||||
| CVE-2026-89460 | 1 Linux | 1 Linux Kernel | 2026-09-14 | 4.4 Medium |
| In the Linux kernel, the following vulnerability has been resolved: s390/cpum_cf: Handle CPU hotplug via prepare/dead callbacks The command 'perf stat -e cycles -- <command>' crashes the kernel when CPUs are hotplug added during that run. Root cause is the allocation of struct cpu_cf_events at first event initialization. The allocation is dynamic and the first event that has task context creates such a structure for each online CPU. This is not sufficient. CPUs may be offline during event creation and can be set online during the perf run time. For example commands # echo 0 > /sys/devices/system/cpu/cpu1/online # perf stat -e cycles -i -- stress-ng -t10s --matrix X # sleep 1 # echo 1 > /sys/devices/system/cpu/cpu1/online create an event for CPUs 0,2-X. Since the events are created with task-context, the scheduler will eventually schedule the program on CPU1. This CPU has not created and initialized any per CPU event infrastructure as that CPU was not online at the time of the perf invocation. Thus when the scheduler runs stress-ng on CPU1, the function cpumf_pmu_add() refers to a NULL pointer: struct cpu_cf_events *cpuhw = this_cpu_cfhw(); This function call is invoked after the task stress-ng has been made runnable on CPU1. And this_cpu_cfhw() returns NULL. The result is a panic: Unable to handle kernel pointer dereference in virtual kernel address space Failing address: 0000000000000000 TEID: 0000000000000483 .... Krnl PSW : 0404d00180000000 000003ef8291fd0c (cpumf_pmu_add+0x3c/0x80) ....

Last Breaking-Event-Address: [<000003ef8291f1d8>] this_cpu_cfhw+0x38/0x40 The issue arises only in per-task context when the CPUMF facility is used and the scheduler picks a random CPU for such a process to run on. The scheduler enables the CPUMF infrastructure via PMU callback functions pmu::add() and pmu::del(). Introduce a CPU hotplug prepare/dead callback pair which creates and removes the per CPU counter data while the CPU is offline. Count the users which track every CPU (cpu == -1), that is perf_event_open() events with task context and /dev/hwctr device sessions, in the new counter cpu_cf_root::tskcnt, protected by pmc_reserve_mutex. This ensures the infrastructure is available when new CPU is selected to run the per-task context process. In cpum_cf_free_root() and cpum_cf_free_cpu() ensure the reference pointer to data structures is set to NULL before the data is freed to prevent interrupt handlers to access stale data.
