The list head is left pointing at\nfreed kmalloc-96 objects.\n\nA second AMDKFD_IOC_CRIU_OP from the same process re-enters: list_empty()\nreads the dangling ->next (use-after-free), the loop walks freed entries,\nand each is kfree()'d again (double-free). This is reachable by an\nunprivileged render-group user via /dev/kfd with no capabilities required.\n\nAdd list_del() before the kfree() so the list is properly emptied. The\nlist_for_each_entry_safe() iterator already caches the next pointer, so\nunlinking during the walk is safe.\n\n(cherry picked from commit 6322d278a298e2c1430b9d2697743d3a04b788b1)\n\n## Affected\n\n- `Linux >= 2a909ae718715b3bac75d945e38dc0a5e4a0f1ba < c8a8d350a273c005a48c64c4519d21b2a51c5ceb`\n- `Linux >= 2a909ae718715b3bac75d945e38dc0a5e4a0f1ba < 506e635aed05dbdeef11e3c59f6e42980cda5b6d`\n- `Linux >= 2a909ae718715b3bac75d945e38dc0a5e4a0f1ba < 838b57b3e7ce8cce0fda56d0861add3d464dd6c8`\n- `Linux >= 2a909ae718715b3bac75d945e38dc0a5e4a0f1ba < 96ac562a9ea3020981f536384711190841c81aa8`\n- `Linux >= 2a909ae718715b3bac75d945e38dc0a5e4a0f1ba < e33a3bd5cb8d0cf1557dee014115f812c9686130`\n- `Linux >= 2a909ae718715b3bac75d945e38dc0a5e4a0f1ba < 8fa5655da368d0306c03e9dc9cda8ae2a7840926`\n- `Linux 5.18`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
