CVE-2025-40022

Summary (CVE-2025-40022) : In the Linux kernel, the af_alg crypto context used 1-bit bitfields of type u32 after a commit that disallowed concurrent writes. Some assignments to fields more/merge wrote values >1, which previously converted to bool, but with 1-bit bitfields the value mod 2 is us...

CVE-2018-14619: Use After Free

A flaw was found in the crypto subsystem of the Linux kernel before version kernel-4.15-rc4. The "null skcipher" was being dropped when each afalgctx was freed instead of when the aeadtfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user bein...
