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: bpf: Fix NULL deref in
map_kptr_match_type for scalar regs Commit ab6c637ad027 ("bpf: Fix a bpf_kptr_xchg() issue with local
kptr") refactored map_kptr_match_type() to branch on btf_is_kernel() before checking base_type(). A scalar
register stored into a kptr slot has no btf, so the btf_is_kernel(reg->btf) call dereferences NULL. Move
the base_type() != PTR_TO_BTF_ID guard before any reg->btf access. (CVE-2026-53032)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.613.77 or later.
