Description

CVE-2026-98180 is a use-after-free vulnerability in the Linux kernel's drm/msm driver. It involves improper freeing of scheduler-containing ringbuffer and VM objects, leading to a scenario where userspace can access freed memory via sync_file or drm_syncobj interfaces. This flaw can cause a kernel slab-use-after-free read, potentially leading to information disclosure or system instability. The issue is fixed by changing the freeing method to kfree_rcu(), ensuring the objects remain valid for an RCU grace period after signaling. The vulnerability affects Linux kernel version 5.15 and has a CVSS score of 7.1 (high severity).
