NVD Description

Note: Versions mentioned in the description apply only to the upstream python3-perf package and not the python3-perf package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

crypto: ccp - Fix a crash due to incorrect cleanup usage of kfree

Annotating a local pointer variable, which will be assigned with the kmalloc-family functions, with the __cleanup(kfree) attribute will make the address of the local variable, rather than the address returned by kmalloc, passed to kfree directly and lead to a crash due to invalid deallocation of stack address. According to other places in the repo, the correct usage should be __free(kfree). The code coincidentally compiled because the parameter type void * of kfree is compatible with the desired type struct { ... } **.
