CVE-2026-46058
Description
A flaw was found in the Linux kernel, specifically within the amphion video processing unit (VPU) driver. A race condition, a situation where multiple operations occur in an unpredictable order, exists in the Video for Linux 2 (V4L2) media-to-memory (m2m) framework. This vulnerability allows a local attacker to exploit a timing issue, leading to a use-after-free error that can cause a kernel panic and result in a denial of service for the system.
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Application Data; Modify Memory; DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands
It may be possible to cause data corruption and possibly execute arbitrary code by modifying global variables or data structures at unexpected times, violating the assumptions of code that uses this global data.
Access Control
Technical Impact: Gain Privileges or Assume Identity
If a signal handler interrupts code that is executing with privileges, it may be possible that the signal handler will also be executed with elevated privileges, possibly making subsequent exploits more severe.
