Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 458845

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: ARM: 9475/1: entry: use byte load for
 KASAN VMAP stack shadow Commit 44e9a3bb76e5 ("ARM: 9430/1: entry: Do a dummy read from VMAP shadow") added
 a dummy read from the KASAN VMAP stack shadow in __switch_to(). The read uses ldr, but the KASAN shadow
 address is byte-granular and is not guaranteed to be word aligned. ARMv5 faults unaligned word loads. With
 CONFIG_KASAN_VMALLOC and CONFIG_VMAP_STACK enabled, ARM926/VersatilePB crashes in __switch_to() with an
 alignment exception before reaching init. Use ldrb for the dummy shadow access. The code only needs to
 fault in the shadow mapping if the stack shadow is missing, so a byte load is sufficient and matches the
 granularity of KASAN shadow memory. (CVE-2026-53343)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
