{"id":"CVE-2026-46051","summary":"md/raid5: fix soft lockup in retry_aligned_read()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmd/raid5: fix soft lockup in retry_aligned_read()\n\nWhen retry_aligned_read() encounters an overlapped stripe, it releases\nthe stripe via raid5_release_stripe() which puts it on the lockless\nreleased_stripes llist. 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() -\u003e 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().","modified":"2026-06-18T03:57:20.579711970Z","published":"2026-05-27T12:57:09.274Z","related":["openSUSE-SU-2026:10954-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46051.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/09880592f5a9dc73377d6eb5ac123537b5f8df49"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1985cb3247e87ff6b8ca4bc5f9626f4f51024507"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4166d5234fe8b6c3c7f796a6c198605356c5b355"},{"type":"WEB","url":"https://git.kernel.org/stable/c/66df9f30673db66ac35145820a8e24906069ae57"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7f9f7c697474268d9ef9479df3ddfe7cdcfbbffc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/80fc6ca2cbde018d52e13f305edcd643911bd94b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/883cc33b7af1c448663287f069ef9dfea001e90f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a9055300e07d9d6800264d3c2560e1d0144689ca"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46051.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46051"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"773ca82fa1ee58dd1bf88b6a5ca385ec83a2cac6"},{"fixed":"66df9f30673db66ac35145820a8e24906069ae57"},{"fixed":"4166d5234fe8b6c3c7f796a6c198605356c5b355"},{"fixed":"a9055300e07d9d6800264d3c2560e1d0144689ca"},{"fixed":"09880592f5a9dc73377d6eb5ac123537b5f8df49"},{"fixed":"80fc6ca2cbde018d52e13f305edcd643911bd94b"},{"fixed":"1985cb3247e87ff6b8ca4bc5f9626f4f51024507"},{"fixed":"883cc33b7af1c448663287f069ef9dfea001e90f"},{"fixed":"7f9f7c697474268d9ef9479df3ddfe7cdcfbbffc"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46051.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.12.0"},{"fixed":"5.10.258"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.209"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.175"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.140"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.27"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.0.4"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-46051.json"}}],"schema_version":"1.7.5"}
