- Summary
- CVE-2022-48670 affecting package kernel for versions less than 5.15.158.2-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
peci: cpu: Fix use-after-free in adev_release()
When auxiliarydeviceadd() returns an error, auxiliarydeviceuninit() is called, which causes refcount for device to be decremented and .release callback will be triggered.
Because adevrelease() re-calls auxiliarydeviceuninit(), it will cause use-after-free: [ 1269.455172] WARNING: CPU: 0 PID: 14267 at lib/refcount.c:28 refcountwarnsaturate+0x110/0x15 [ 1269.464007] refcountt: underflow; use-after-free.
