| CVE-2025-38655 | 1 Linux | 1 Linux Kernel | 2025-11-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: pinctrl: canaan: k230: add NULL check in DT parse Add a NULL check for the return value of of_get_property() when retrieving the "pinmux" property in the group parser. This avoids a potential NULL pointer dereference if the property is missing from the device tree node. Also fix a typo ("sintenel") in the device ID match table comment, correcting it to "sentinel". | ||||

| In the Linux kernel, the following vulnerability has been resolved: pinctrl: canaan: k230: Fix order of DT parse and pinctrl register Move DT parse before pinctrl register. This ensures that device tree parsing is done before calling devm_pinctrl_register() to prevent using uninitialized pin resources. | ||||

| In the Linux kernel, the following vulnerability has been resolved: arm64: dts: qcom: qcs615: fix a crash issue caused by infinite loop for Coresight An infinite loop has been created by the Coresight devices. When only a source device is enabled, the coresight_find_activated_sysfs_sink function is recursively invoked in an attempt to locate an active sink device, ultimately leading to a stack overflow and system crash. Therefore, disable the replicator1 to break the infinite loop and prevent a potential stack overflow. replicator1_out -> funnel_swao_in6 -> tmc_etf_swao_in -> tmc_etf_swao_out | | replicator1_in replicator_swao_in | | replicator0_out1 replicator_swao_out0 | | replicator0_in funnel_in1_in3 | | tmc_etf_out <- tmc_etf_in <- funnel_merg_out <- funnel_merg_in1 <- funnel_in1_out [call trace] dump_backtrace+0x9c/0x128 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 dump_stack+0x18/0x28 panic+0x340/0x3b0 nmi_panic+0x94/0xa0 panic_bad_stack+0x114/0x138 handle_bad_stack+0x34/0xb8 __bad_stack+0x78/0x80 coresight_find_activated_sysfs_sink+0x28/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] ... coresight_find_activated_sysfs_sink+0x5c/0xa0 [coresight] coresight_enable_sysfs+0x80/0x2a0 [coresight] side effect after the change: Only trace data originating from AOSS can reach the ETF_SWAO and EUD sinks. | ||||
| CVE-2025-38648 | 1 Linux | 1 Linux Kernel | 2025-11-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: spi: stm32: Check for cfg availability in stm32_spi_probe The stm32_spi_probe function now includes a check to ensure that the pointer returned by of_device_get_match_data is not NULL before accessing its members. This resolves a warning where a potential NULL pointer dereference could occur when accessing cfg->has_device_mode. Before accessing the 'has_device_mode' member, we verify that 'cfg' is not NULL. If 'cfg' is NULL, an error message is logged. This change ensures that the driver does not attempt to access configuration data if it is not available, thus preventing a potential system crash due to a NULL pointer dereference. | ||||
| CVE-2022-50251 | 1 Linux | 1 Linux Kernel | 2025-11-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mmc: vub300: fix return value check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path. So fix this by checking the return value and goto error path which will call mmc_free_host(), besides, the timer added before mmc_add_host() needs be del. And this patch fixes another missing call mmc_free_host() if usb_control_msg() fails. | ||||

| In the Linux kernel, the following vulnerability has been resolved: Revert "drm/gem-framebuffer: Use dma_buf from GEM object instance" This reverts commit cce16fcd7446dcff7480cd9d2b6417075ed81065. The dma_buf field in struct drm_gem_object is not stable over the object instance's lifetime. The field becomes NULL when user space releases the final GEM handle on the buffer object. This resulted in a NULL-pointer deref. Workarounds in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers") and commit f6bfc9afc751 ("drm/framebuffer: Acquire internal references on GEM handles") only solved the problem partially. They especially don't work for buffer objects without a DRM framebuffer associated. Hence, this revert to going back to using .import_attach->dmabuf. v3: - cc stable | ||||

| In the Linux kernel, the following vulnerability has been resolved: iio: fix potential out-of-bound write The buffer is set to 20 characters. If a caller write more characters, count is truncated to the max available space in "simple_write_to_buffer". To protect from OoB access, check that the input size fit into buffer and add a zero terminator after copy to the end of the copied data. | ||||

| In the Linux kernel, the following vulnerability has been resolved: i2c: core: Fix double-free of fwnode in i2c_unregister_device() Before commit df6d7277e552 ("i2c: core: Do not dereference fwnode in struct device"), i2c_unregister_device() only called fwnode_handle_put() on of_node-s in the form of calling of_node_put(client->dev.of_node). But after this commit the i2c_client's fwnode now unconditionally gets fwnode_handle_put() on it. When the i2c_client has no primary (ACPI / OF) fwnode but it does have a software fwnode, the software-node will be the primary node and fwnode_handle_put() will put() it. But for the software fwnode device_remove_software_node() will also put() it leading to a double free: [ 82.665598] ------------[ cut here ]------------ [ 82.665609] refcount_t: underflow; use-after-free.

| CVE-2025-38730 | 1 Linux | 1 Linux Kernel | 2025-11-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: io_uring/net: commit partial buffers on retry Ring provided buffers are potentially only valid within the single execution context in which they were acquired. io_uring deals with this and invalidates them on retry. But on the networking side, if MSG_WAITALL is set, or if the socket is of the streaming type and too little was processed, then it will hang on to the buffer rather than recycle or commit it. This is problematic for two reasons: 1) If someone unregisters the provided buffer ring before a later retry, then the req->buf_list will no longer be valid. 2) If multiple sockers are using the same buffer group, then multiple receives can consume the same memory. This can cause data corruption in the application, as either receive could land in the same userspace buffer. Fix this by disallowing partial retries from pinning a provided buffer across multiple executions, if ring provided buffers are used. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: ftgmac100: fix potential NULL pointer access in ftgmac100_phy_disconnect After the call to phy_disconnect() netdev->phydev is reset to NULL. So fixed_phy_unregister() would be called with a NULL pointer as argument. Therefore cache the phy_device before this call. | ||||
| CVE-2025-38722 | 1 Linux | 1 Linux Kernel | 2025-11-25 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: habanalabs: fix UAF in export_dmabuf() As soon as we'd inserted a file reference into descriptor table, another thread could close it. That's fine for the case when all we are doing is returning that descriptor to userland (it's a race, but it's a userland race and there's nothing the kernel can do about it). However, if we follow fd_install() with any kind of access to objects that would be destroyed on close (be it the struct file itself or anything destroyed by its ->release()), we have a UAF. dma_buf_fd() is a combination of reserving a descriptor and fd_install(). habanalabs export_dmabuf() calls it and then proceeds to access the objects destroyed on close. In particular, it grabs an extra reference to another struct file that will be dropped as part of ->release() for ours; that "will be" is actually "might have already been". Fix that by reserving descriptor before anything else and do fd_install() only when everything had been set up. As a side benefit, we no longer have the failure exit with file already created, but reference to underlying file (as well as ->dmabuf_export_cnt, etc.) not grabbed yet; unlike dma_buf_fd(), fd_install() can't fail. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: hibmcge: fix rtnl deadlock issue Currently, the hibmcge netdev acquires the rtnl_lock in pci_error_handlers.reset_prepare() and releases it in pci_error_handlers.reset_done(). However, in the PCI framework: pci_reset_bus - __pci_reset_slot - pci_slot_save_and_disable_locked - pci_dev_save_and_disable - err_handler->reset_prepare(dev); In pci_slot_save_and_disable_locked(): list_for_each_entry(dev, &slot->bus->devices, bus_list) { if (!dev->slot || dev->slot!= slot) continue; pci_dev_save_and_disable(dev); if (dev->subordinate) pci_bus_save_and_disable_locked(dev->subordinate); } This will iterate through all devices under the current bus and execute err_handler->reset_prepare(), causing two devices of the hibmcge driver to sequentially request the rtnl_lock, leading to a deadlock. Since the driver now executes netif_device_detach() before the reset process, it will not concurrently with other netdev APIs, so there is no need to hold the rtnl_lock now. Therefore, this patch removes the rtnl_lock during the reset process and adjusts the position of HBG_NIC_STATE_RESETTING to ensure that multiple resets are not executed concurrently. | ||||
| CVE-2025-39695 | 1 Linux | 1 Linux Kernel | 2025-11-25 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Flush delayed SKBs while releasing RXE resources When skb packets are sent out, these skb packets still depends on the rxe resources, for example, QP, sk, when these packets are destroyed. If these rxe resources are released when the skb packets are destroyed, the call traces will appear. To avoid skb packets hang too long time in some network devices, a timestamp is added when these skb packets are created. If these skb packets hang too long time in network devices, these network devices can free these skb packets to release rxe resources. | ||||
