Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

CVE-2026-80583 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 5.15.218, 6.1.185, 6.6.154, 6.12.106, 6.18.47, 7.1.10 or higher.
Overview
Affected versions of this package are vulnerable to Out-of-Bounds in the tx_macro_dec_mode_get and tx_macro_dec_mode_put functions. An attacker can cause memory corruption and denial of service by performing crafted ioctl operations on the DEC MODE controls, leading to out-of-bounds read and write in kernel memory. This is only exploitable if the attacker has local access to the ALSA control device, typically granted to the audio group on affected systems.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
