Linux: >> Linux Kernel >> 6.0.11 Security Vulnerabilities
In the Linux kernel, the following vulnerability has been resolved:
wifi: brcmfmac: fix potential memory leak in brcmf_netdev_start_xmit()
The brcmf_netdev_start_xmit() returns NETDEV_TX_OK without freeing skb
in case of pskb_expand_head() fails, add dev_kfree_skb() to fix it.
Compile tested only.

In the Linux kernel, the following vulnerability has been resolved:
rtc: msc313: Fix function prototype mismatch in msc313_rtc_probe()
With clang's kernel control flow integrity (kCFI, CONFIG_CFI_CLANG),
indirect call targets are validated against the expected function
pointer prototype to make sure the call target is valid to help mitigate
ROP attacks. If they are not identical, there is a failure at run time,
which manifests as either a kernel panic or thread getting killed.
msc313_rtc_probe() was passing clk_disable_unprepare() directly, which
did not have matching prototypes for devm_add_action_or_reset()'s
callback argument. Refactor to use devm_clk_get_enabled() instead.
This was found as a result of Clang's new -Wcast-function-type-strict
flag, which is more sensitive than the simpler -Wcast-function-type,
which only checks for type width mismatches.

In the Linux kernel, the following vulnerability has been resolved:
ACPI: processor: idle: Check acpi_fetch_acpi_dev() return value
The return value of acpi_fetch_acpi_dev() could be NULL, which would
cause a NULL pointer dereference to occur in acpi_device_hid().

In the Linux kernel, the following vulnerability has been resolved:
perf/x86/intel/uncore: Fix reference count leak in hswep_has_limit_sbox()
pci_get_device() will increase the reference count for the returned
'dev'. We need to call pci_dev_put() to decrease the reference count.
Since 'dev' is only used in pci_read_config_dword(), let's add
pci_dev_put() right after it.

In the Linux kernel, the following vulnerability has been resolved:
coresight: trbe: remove cpuhp instance node before remove cpuhp state
cpuhp_state_add_instance() and cpuhp_state_remove_instance() should
be used in pairs. Or there will lead to the warn on
cpuhp_remove_multi_state() since the cpuhp_step list is not empty.
The following is the error log with 'rmmod coresight-trbe':

In the Linux kernel, the following vulnerability has been resolved:
ASoC: sof_es8336: fix possible use-after-free in sof_es8336_remove()
sof_es8336_remove() calls cancel_delayed_work(). However, that
function does not wait until the work function finishes. This
means that the callback function may still be running after
the driver's remove function has finished, which would result
in a use-after-free.
Fix by calling cancel_delayed_work_sync(), which ensures that
the work is properly cancelled, no longer running, and unable
to re-schedule itself.
