CVE-2026-45959

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the crypto: ccp component where a local pointer variable assigned via kmalloc-family functions is incorrectly annotated with the cleanup(kfree) attribute. This causes the address of the local variable itself to be passed to the kfree() function instead of the address returned by kmalloc, resulting in a crash due to the invalid deallocation of a stack address. The correct implementation requires the use of free(kfree).

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
