CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
media: cxusb: no longer judge rbuf when the write fails
syzbot reported a uninit-value in cxusb_i2c_xfer. [1]
Only when the write operation of usb_bulk_msg() in dvb_usb_generic_rw()
succeeds and rlen is greater than 0, the read operation of usb_bulk_msg()
will be executed to read rlen bytes of data from the dvb device into the
rbuf.
In this case, although rlen is 1, the write operation failed which resulted
in the dvb read operation not being executed, and ultimately variable i was
not initialized.

| In the Linux kernel, the following vulnerability has been resolved:
net: ch9200: fix uninitialised access during mii_nway_restart
In mii_nway_restart() the code attempts to call
mii->mdio_read which is ch9200_mdio_read(). ch9200_mdio_read()
utilises a local buffer called "buff", which is initialised
with control_read(). However "buff" is conditionally
initialised inside control_read():
if (err == size) {
memcpy(data, buf, size);
}
If the condition of "err == size" is not met, then
"buff" remains uninitialised. Once this happens the
uninitialised "buff" is accessed and returned during
ch9200_mdio_read():
return (buff[0] | buff[1] << 8);
The problem stems from the fact that ch9200_mdio_read()
ignores the return value of control_read(), leading to
uinit-access of "buff".
To fix this we should check the return value of
control_read() and return early on error. |

libnvdimm/labels: Fix divide error in nd_label_data_init()
If a faulty CXL memory device returns a broken zero LSA size in its
memory device information (Identify Memory Device (Opcode 4000h), CXL
spec. 3.1, 8.2.9.9.1.1), a divide error occurs in the libnvdimm
driver:
Oops: divide error: 0000 [#1] PREEMPT SMP NOPTI
RIP: 0010:nd_label_data_init+0x10e/0x800 [libnvdimm]
Code and flow:
1) CXL Command 4000h returns LSA size = 0
2) config_size is assigned to zero LSA size (CXL pmem driver):
drivers/cxl/pmem.c: .config_size = mds->lsa_size,
3) max_xfer is set to zero (nvdimm driver):
drivers/nvdimm/label.c: max_xfer = min_t(size_t, ndd->nsarea.max_xfer, config_size);
4) A subsequent DIV_ROUND_UP() causes a division by zero:
drivers/nvdimm/label.c: /* Make our initial read size a multiple of max_xfer size */
drivers/nvdimm/label.c: read_size = min(DIV_ROUND_UP(read_size, max_xfer) * max_xfer,
drivers/nvdimm/label.c- config_size);
Fix this by checking the config size parameter by extending an
existing check. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: brcm80211: fmac: Add error handling for brcmf_usb_dl_writeimage()
The function brcmf_usb_dl_writeimage() calls the function
brcmf_usb_dl_cmd() but dose not check its return value. The
'state.state' and the 'state.bytes' are uninitialized if the
function brcmf_usb_dl_cmd() fails. It is dangerous to use
uninitialized variables in the conditions.
Add error handling for brcmf_usb_dl_cmd() to jump to error
handling path if the brcmf_usb_dl_cmd() fails and the
'state.state' and the 'state.bytes' are uninitialized.
Improve the error message to report more detailed error
information. |
| In the Linux kernel, the following vulnerability has been resolved:
ipvs: fix uninit-value for saddr in do_output_route4
syzbot reports for uninit-value for the saddr argument [1].
commit 4754957f04f5 ("ipvs: do not use random local source address for
tunnels") already implies that the input value of saddr
should be ignored but the code is still reading it which can prevent
to connect the route. Fix it by changing the argument to ret_saddr.

It is because that skb->len requires at least sizeof(struct qrtr_ctrl_pkt)
in qrtr_tx_resume(). And skb->len equals to size in qrtr_endpoint_post().
But size is less than sizeof(struct qrtr_ctrl_pkt) when qrtr_cb->type
equals to QRTR_TYPE_RESUME_TX in qrtr_endpoint_post() under the syzbot
scenario. This triggers the uninit variable access bug.
Add size check when qrtr_cb->type equals to QRTR_TYPE_RESUME_TX in
qrtr_endpoint_post() to fix the bug. |

wifi: ath11k: fix deinitialization of firmware resources
Currently, in ath11k_ahb_fw_resources_init(), iommu domain
mapping is done only for the chipsets having fixed firmware
memory. Also, for such chipsets, mapping is done only if it
does not have TrustZone support.
During deinitialization, only if TrustZone support is not there,
iommu is unmapped back. However, for non fixed firmware memory
chipsets, TrustZone support is not there and this makes the
condition check to true and it tries to unmap the memory which
was not mapped during initialization.
This leads to the following trace -

This can be reproduced by probing an AHB chipset which is not
having a fixed memory region. During reboot (or rmmod) trace
can be seen.
Fix this issue by adding a condition check on firmware fixed memory
hw_param as done in the counter initialization function.

For filenames that begin with . and are between 2 and 5 characters long,

A splat from kmem_cache_destroy() was seen with a kernel prior to
commit ee2653bbe89d ("iommu/vt-d: Remove domain and devinfo mempool")
when there was a failure in init_dmars(), because the iommu_domain

still is a leak of the si_domain memory if init_dmars() fails. So
clean up si_domain in the init_dmars() error path. |

In the function rxe_create_qp(), rxe_qp_from_init() is called to

If an error occures before this point then the unwind will call

The issue here is that board file loading happens after ath11k_pci_probe()
succesfully returns (ath11k initialisation happends asynchronously) and the
suspend handler is still enabled, of course failing as ath11k is not properly
initialised. Fix this by checking ATH11K_FLAG_QMI_FAIL during both suspend and
resume.

| FFmpeg 4.4 through 9.0.2 contains a use of uninitialized variable vulnerability in the CDXL decoder that leaks stack memory into decoded pixels via unfilled HAM palette entries. Attackers can craft a type-0 CDXL file whose HAM pixels select unfilled new_palette entries in cdxl_decode_ham8() or cdxl_decode_ham6(), exposing stack bytes and pointer fragments in the BGR24 output. |
| In the Linux kernel, the following vulnerability has been resolved:
soc/tegra: pmc: Fix uninitialised clock rate
For legacy 32-bit Tegra devices, the warning in the
tegra_pmc_enter_suspend_mode() function is being triggered because the
early_pmc->rate variable is never configured and hence, always 0. This
issue started occurring after updating the PMC driver to create the PMC
context dynamically which causes the 'rate' to be set in the new dynamic
context, but missed updating the rate in the early PMC context.
Fix this by initialising the early_pmc->rate variable for 32-bit Tegra
devices when the rate for the PMC context is initialised.
