In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Synchronize devfreq_monitor_[start/stop]
There is a chance if a frequent switch of the governor
done in a loop result in timer list corruption where
timer cancel being done from two place one from
cancel_delayed_work_sync() and followed by expire_timers()
can be seen from the traces[1].
while true
do
echo "simple_ondemand" > /sys/class/devfreq/1d84000.ufshc/governor
echo "performance" > /sys/class/devfreq/1d84000.ufshc/governor
done
It looks to be issue with devfreq driver where
device_monitor_[start/stop] need to synchronized so that
delayed work should get corrupted while it is either
being queued or running or being cancelled.
Let's use polling flag and devfreq lock to synchronize the
queueing the timer instance twice and work data being
corrupted.

did not properly validate H2C PDU data, leading to a null pointer
dereference vulnerability. A remote attacker could use this to cause a
denial of service (system crash). (CVE-2023-6356, CVE-2023-6535,
CVE-2023-6536)
Chenyuan Yang discovered that the RDS Protocol implementation in the Linux
kernel contained an out-of-bounds read vulnerability. An attacker could use
this to possibly cause a denial of service (system crash). (CVE-2024-23849)

kernel: PM / devfreq: Synchronize devfreq_monitor_[start/stop]
In the Linux kernel, the following vulnerability has been resolved:
PM / devfreq: Synchronize devfreq_monitor_[start/stop]
There is a chance if a frequent switch of the governor
done in a loop result in timer list corruption where
timer cancel being done from two place one from
cancel_delayed_work_sync() and followed by expire_timers()
can be seen from the traces[1].
