CVE-2026-23076

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: ctxfi: Fix potential OOB access in audio mixer handling<br /> <br /> In the audio mixer handling code of ctxfi driver, the conf field is<br /> used as a kind of loop index, and it&amp;#39;s referred in the index callbacks<br /> (amixer_index() and sum_index()).<br /> <br /> As spotted recently by fuzzers, the current code causes OOB access at<br /> those functions.<br /> | UBSAN: array-index-out-of-bounds in /build/reproducible-path/linux-6.17.8/sound/pci/ctxfi/ctamixer.c:347:48<br /> | index 8 is out of range for type &amp;#39;unsigned char [8]&amp;#39;<br /> <br /> After the analysis, the cause was found to be the lack of the proper<br /> (re-)initialization of conj field.<br /> <br /> This patch addresses those OOB accesses by adding the proper<br /> initializations of the loop indices.
