CVE-2026-63805

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

Description An issue exists in the Linux kernel crypto NX driver where a type mismatch occurs in context exit functions. Specifically, the function nx crypto ctx shash exit() calls nx crypto ctx exit() using crypto shash ctx(), which returns a nx crypto ctx * instead of the expected crypto tfm *. This mismatch can lead to a kernel oops (kernel panic) due to invalid kernel data access. A similar issue is present in the nx crypto ctx skcipher exit() function. This problem has been observed on IBM PowerPC architectures when using AF ALG.

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