CVE-2026-43336

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

Description A flaw exists in the lib/crypto component where the local variable permuted state is not cleared before leaving its scope. Because the ChaCha permutation is invertible, this variable can be used to compute the original state and subsequently recover the key after the permutation process is complete.

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