Linux Kernel Out-of-Bounds Read Vulnerability (CVE-2024-53150)

A local attacker, with a low-privilege account, can achieve full data confidentiality loss, complete denial of service or system unavailability. Federal agencies are required to remediate by 2025-04-30 under CISA BOD 22-01.

This is a Out-of-bounds Read (CWE-125) vulnerability in Linux Kernel. In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix out of bounds reads when finding clock sources The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check. Exploitation requires local access, low attack complexity, a low-privilege authenticated account, and no user interaction required.

Probably yes if any of these apply:

CISA added this CVE to the Known Exploited Vulnerabilities catalog on 2025-04-09 based on evidence of active exploitation in the wild. Federal agencies required to remediate by 2025-04-30.
