Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: crypto: authencesn - reject short
ahash digests during instance creation authencesn requires either a zero authsize or an authsize of at
least 4 bytes because the ESN encrypt/decrypt paths always move 4 bytes of high-order sequence number data
at the end of the authenticated data. While crypto_authenc_esn_setauthsize() already rejects explicit non-
zero authsizes in the range 1..3, crypto_authenc_esn_create() still copied auth->digestsize into
inst->alg.maxauthsize without validating it. The AEAD core then initialized the tfm's default authsize
from that value. As a result, selecting an ahash with digest size 1..3, such as cbcmac(cipher_null),
exposed authencesn instances whose default authsize was invalid even though setauthsize() would have
rejected the same value. AF_ALG could then trigger the ESN tail handling with a too-short tag and hit an
out-of-bounds access. Reject authencesn instances whose ahash digest size is in the invalid non-zero range
1..3 so that no tfm can inherit an unsupported default authsize. (CVE-2026-46033)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.40 or later.
