medium Tenable Self-Hosted Container Security Plugin ID 457544

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: mtd: Avoid boot crash in RedBoot
 partition table parser Given CONFIG_FORTIFY_SOURCE=y and a recent compiler, commit 439a1bcac648 ("fortify:
 Use __builtin_dynamic_object_size() when available") produces the warning below and an oops. Searching for
 RedBoot partition table in 50000000.flash at offset 0x7e0000 ------------[ cut here ]------------ WARNING:
 lib/string_helpers.c:1035 at 0xc029e04c, CPU#0: swapper/0/1 memcmp: detected buffer overflow: 15 byte read
 of buffer size 14 Modules linked in: CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.19.0 #1 NONE As
 Kees said, "'names' is pointing to the final 'namelen' many bytes of the allocation ... 'namelen' could be
 basically any length at all. This fortify warning looks legit to me -- this code used to be reading beyond
 the end of the allocation." Since the size of the dynamic allocation is calculated with strlen() we can
 use strcmp() instead of memcmp() and remain within bounds. (CVE-2026-23474)

Solution

Update the linux library and its related packages to version 6.1.170-1 or later.
