FFmpeg versions 0.7.1 through 8.1.2 contain an out-of-bounds read vulnerability in the S/PDIF muxer that allows attackers to access memory beyond buffer boundaries by supplying a crafted DTS stream with a coresize value larger than the actual packet length. Attackers can exploit the missing bound...

CVE-2026-64486

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA cmipci component. This vulnerability occurs because the sndcmipcispdifcontrols function fails to check the return value of sndctlnew1, which can return a null pointer if memory allocation fails. A local attacker could...

SUSE CVE-2026-46049

In the Linux kernel, the following vulnerability has been resolved: ALSA: ctxfi: Add fallback to default RSR for S/PDIF spdifpassthruplaybackgetresources uses atc-pllrate as the RSR for the MSR calculation loop. However, pllrate is only updated in atcpllinit and not in hwpllinit, so it remains 0...

CVE-2026-46049

A flaw was found in the ALSA Advanced Linux Sound Architecture ctxfi driver in the Linux kernel. When processing S/PDIF Sony/Philips Digital Interface Format passthrough playback at 32000 Hz, a missing update to the pllrate can cause an infinite loop. This can lead to a denial of service DoS for ...

CVE-2026-46049

CVE-2026-46049 concerns the Linux kernel ALSA ctxfi driver (S/PDIF path). The issue arises in spdif_passthru_playback_setup() when pll_rate is not updated (remains 0), causing the MSR calculation loop to spin if 32000 Hz is skipped. The fix adds a fallback: if atc->pll_rate is 0, use atc->r...
