CVE-2026-46215 – Linux
CVSS 7.8
IMPORTANT
Zero Day – Immediate Deployment
“A race condition in the kernel can turn a routine operation into a serious memory safety risk.”
The Linux kernel has been patched for CVE-2026-46215, a race condition in the DRM handle-management process. Concurrent operations could leave a dangling handle that was later dereferenced, resulting in a use-after-free condition. The update prevents the old handle from being reused while PRIME operations are completed.
The CVSS score is 7.8, which is High severity. Public proof-of-concept code is available, increasing the risk that the vulnerability could be tested or adapted against unpatched systems.
