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: netfilter: nfnetlink_osf: fix out-of-
 bounds read on option matching In nf_osf_match(), the nf_osf_hdr_ctx structure is initialized once and
 passed by reference to nf_osf_match_one() for each fingerprint checked. During TCP option parsing,
 nf_osf_match_one() advances the shared ctx->optp pointer. If a fingerprint perfectly matches, the function
 returns early without restoring ctx->optp to its initial state. If the user has configured
 NF_OSF_LOGLEVEL_ALL, the loop continues to the next fingerprint. However, because ctx->optp was not
 restored, the next call to nf_osf_match_one() starts parsing from the end of the options buffer. This
 causes subsequent matches to read garbage data and fail immediately, making it impossible to log more than
 one match or logging incorrect matches. Instead of using a shared ctx->optp pointer, pass the context as a
 constant pointer and use a local pointer (optp) for TCP option traversal. This makes nf_osf_match_one()
 strictly stateless from the caller's perspective, ensuring every fingerprint check starts at the correct
 option offset. (CVE-2026-52999)

Solution

Update the sys-kernel/csql-kernel-6_1 library and its related packages to version 18613.613.77 or later.
