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: ALSA: ctxfi: Fix potential OOB access
 in audio mixer handling In the audio mixer handling code of ctxfi driver, the conf field is used as a kind
 of loop index, and it's referred in the index callbacks (amixer_index() and sum_index()). As spotted
 recently by fuzzers, the current code causes OOB access at those functions. | UBSAN: array-index-out-of-
 bounds in /build/reproducible-path/linux-6.17.8/sound/pci/ctxfi/ctamixer.c:347:48 | index 8 is out of
 range for type 'unsigned char [8]' After the analysis, the cause was found to be the lack of the proper
 (re-)initialization of conj field. This patch addresses those OOB accesses by adding the proper
 initializations of the loop indices. (CVE-2026-23076)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
