Echo: linux: security update to 6.12.25-1

medium Tenable Cloud Security Plugin ID 465933

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: LoongArch: BPF: Don't override
 subprog's return value The verifier test `calls: div by 0 in subprog` triggers a panic at the ld.bu
 instruction. The ld.bu insn is trying to load byte from memory address returned by the subprog. The
 subprog actually set the correct address at the a5 register (dedicated register for BPF return values).
 But at commit 73c359d1d356 ("LoongArch: BPF: Sign-extend return values") we also sign extended a5 to the
 a0 register (return value in LoongArch). For function call insn, we later propagate the a0 register back
 to a5 register. This is right for native calls but wrong for bpf2bpf calls which expect zero-extended
 return value in a5 register. So only move a0 to a5 for native calls (i.e. non-BPF_PSEUDO_CALL).
 (CVE-2025-22048)

Solution

Update the linux library and its related packages to version 6.12.25-1 or later.
