CVE-2025-71099 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Fix potential UAF in xe_oa_add_config_ioctl() In xe_oa_add_config_ioctl(), we accessed oa_config->id after dropping metrics_lock. Since this lock protects the lifetime of oa_config, an attacker could guess the id and call xe_oa_remove_config_ioctl() with perfect timing, freeing oa_config before we dereference it, leading to a potential use-after-free. Fix this by caching the id in a local variable while holding the lock. v2: (Matt A) - Dropped mutex_unlock(&oa->metrics_lock) ordering change from xe_oa_remove_config_ioctl() (cherry picked from commit 28aeaed130e8e587fd1b73b6d66ca41ccc5a1a31)
A use-after-free vulnerability has been identified in the Linux kernel's Direct Rendering Manager (DRM) XE component, specifically within the 'xe_oa_add_config_ioctl' function. The issue arises because the function accesses the 'oa_config->id' after releasing the 'metrics_lock', which is crucial for managing the lifetime of 'oa_config'. This timing flaw could allow an attacker to predict the 'id' and invoke 'xe_oa_remove_config_ioctl' to free 'oa_config' before it is accessed, leading to a potential use-after-free condition. The vulnerability affects Linux kernel versions 6.11 and later.
Users can upgrade to the latest version of the Linux kernel to address this vulnerability. The patched version is available in the Linux stable tree.
