A vulnerability in the Linux kernel's drm/v3d component involves improper reference counting in the global performance monitor management. (CVE-2026-53141)
A vulnerability in the Linux kernel's drm/v3d component involves improper reference counting in the global performance monitor management. Specifically, certain error paths and operations in the SET_GLOBAL ioctl and related functions fail to release references properly, leading to reference leaks. This issue has been resolved by explicitly releasing these references.
AI Analysis
Technical Summary
The Linux kernel's drm/v3d driver had a flaw in its global performance monitor reference counting. The function v3d_perfmon_find() increments the reference count on the performance monitor it returns, but v3d_perfmon_set_global_ioctl() and v3d_perfmon_delete() do not release these references correctly on several code paths, including error handling and clearing global settings. This results in reference leaks that could affect system stability or resource management. The vulnerability has been fixed by ensuring all references are explicitly released.
Potential Impact
The vulnerability does not impact confidentiality or integrity but affects availability due to reference leaks in the performance monitor management. This can lead to resource exhaustion or degraded system performance in affected Linux kernel versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since this is a Linux kernel vulnerability, monitor official Linux kernel releases and security advisories for patches addressing this issue. Apply updates promptly once available to resolve the reference counting leaks.
