In the Linux kernel, the following vulnerability has been resolved:
Revert "hwmon: (ibmpex) fix use-after-free in high/low store"
This reverts commit 6946c726c3f4c36f0f049e6f97e88c510b15f65d.
Jean Delvare points out that the patch does not completely
fix the reported problem, that it in fact introduces a
(new) race condition, and that it may actually not be needed in
the first place.
Various AI reviews agree. Specific and relevant AI feedback:
"
This reordering sets the driver data to NULL before removing the sensor
attributes in the loop below.
ibmpex_show_sensor() retrieves this driver data via dev_get_drvdata() but
does not check if it is NULL before dereferencing it to access
data->sensors[].
If a userspace process reads a sensor file (like temp1_input) while this
delete function is running, could it race with the dev_set_drvdata(...,
NULL) call here and crash in ibmpex_show_sensor()?
Would it be safer to keep the original order where device_remove_file() is
called before clearing the driver data? device_remove_file() should wait
for any active sysfs callbacks to complete, which might already prevent the
use-after-free this patch intends to fix.
"
Revert the offending patch. If it can be shown that the originally reported
alleged race condition does indeed exist, it can always be re-introduced
with a complete fix.

kernel: Revert "hwmon: (ibmpex) fix use-after-free in high/low store"
A flaw was found in the Linux kernel's `hwmon: ibmpex` driver. A race condition exists where a userspace process reading a sensor file can attempt to access freed memory if it races with a device deletion operation. This use-after-free vulnerability could allow a local attacker to cause a system crash, leading to a Denial of Service (DoS).
