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 ld_{abs,ind} failure path
 analysis in subprogs Usage of ld_{abs,ind} instructions got extended into subprogs some time ago via
 commit 09b28d76eac4 ("bpf: Add abnormal return checks."). These are only allowed in subprograms when the
 latter are BTF annotated and have scalar return types. The code generator in bpf_gen_ld_abs() has an
 abnormal exit path (r0=0 + exit) from legacy cBPF times. While the enforcement is on scalar return types,
 the verifier must also simulate the path of abnormal exit if the packet data load via ld_{abs,ind} failed.
 This is currently not the case. Fix it by having the verifier simulate both success and failure paths, and
 extend it in similar ways as we do for tail calls. The success path (r0=unknown, continue to next insn) is
 pushed onto stack for later validation and the r0=0 and return to the caller is done on the fall-through
 side. (CVE-2026-53090)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18867.584.3 or later.
