In the next raid5d loop iteration,\nrelease_stripe_list() drains the stripe onto handle_list (since\nSTRIPE_HANDLE is set by the original IO), but retry_aligned_read()\nruns before handle_active_stripes() and removes the stripe from\nhandle_list via find_get_stripe() -> list_del_init(). This prevents\nhandle_stripe() from ever processing the stripe to resolve the\noverlap, causing an infinite loop and soft lockup.\n\nFix this by using __release_stripe() with temp_inactive_list instead\nof raid5_release_stripe() in the failure path, so the stripe does not\ngo through the released_stripes llist. This allows raid5d to break out\nof its loop, and the overlap will be resolved when the stripe is\neventually processed by handle_stripe().\n\n## Affected\n\n- `linux_kernel >= 3.12, < 5.10.258`\n- `linux_kernel >= 5.11, < 5.15.209`\n- `linux_kernel >= 5.16, < 6.1.175`\n- `linux_kernel >= 6.2, < 6.6.140`\n- `linux_kernel >= 6.7, < 6.12.86`\n- `linux_kernel >= 6.13, < 6.18.27`\n- `linux_kernel >= 6.19, < 7.0.4`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `linux_kernel 7.0.4`","depth":"sunlit","depthScore":30,"depthScoreParts":{"impact":30.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
