"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/oa: Fix potential UAF in xe_oa_add_config_ioctl()\n\nIn xe_oa_add_config_ioctl(), we accessed oa_config->id after dropping\nmetrics_lock. Since this lock protects the lifetime of oa_config, an\nattacker could guess the id and call xe_oa_remove_config_ioctl() with\nperfect timing, freeing oa_config before we dereference it, leading to\na potential use-after-free.\n\nFix this by caching the id in a local variable while holding the lock.\n\nv2: (Matt A)\n- Dropped mutex_unlock(&oa->metrics_lock) ordering change from\n xe_oa_remove_config_ioctl()\n\n(cherry picked from commit 28aeaed130e8e587fd1b73b6d66ca41ccc5a1a31)"

"value": "AV:L - The vulnerability is reached through DRM_XE_OBSERVATION add/remove ioctls on a local Xe DRM device node; no network or physical path exists.\nAC:L - The attacker controls concurrent add and remove operations, and IDs are predictable because the IDR starts at 1 and selects the lowest available value. The race can be attempted repeatedly without relying on victim-controlled state.\nPR:L - The supported observation_paranoid=0 configuration permits ordinary render-node clients without capabilities. Although the default requires initial-namespace CAP_PERFMON or CAP_SYS_ADMIN, the higher-severity reasonable deployment requires only an unprivileged local account with device access.\nUI:N - The attacker triggers both sides of the race directly through concurrent ioctls, without any victim action.\nS:U - Exploitation affects the host kernel within its existing security authority and does not inherently cross a VM, IOMMU, or separate authorization boundary.\nC:H - The stale oa_config can be dereferenced after RCU reclamation and attacker-directed slab reuse, potentially exposing kernel memory through the reclaimed ID or debug UUID accesses.\nI:H - The use-after-free permits attacker-influenced heap reuse and must be treated as potentially yielding memory-corruption primitives, arbitrary writes, or kernel code execution.\nA:H - Dereferencing reclaimed or poisoned slab memory can cause a kernel oops or panic, and the attacker can repeatedly trigger the race."
