The VPD update path serializes the same call\nunder optrom_mutex, so this reset path can interleave its flash register\naccesses with a concurrent VPD or optrom flash operation and corrupt the\nreads.\n\nHold ha->optrom_mutex across the get_flash_version() call to match the\nVPD update path.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/31bf2714abbb0aa5a8a03d15038f8920e1c74b21","tags":[]},{"url":"https://git.kernel.org/stable/c/33735490789e5417851752974c0b1d23125559cd","tags":[]},{"url":"https://git.kernel.org/stable/c/75460967619eda720c9a03767729157ffd171d8c","tags":[]},{"url":"https://git.kernel.org/stable/c/8d116137119371349fb09685fe05413d8fc92efe","tags":[]},{"url":"https://git.kernel.org/stable/c/9cef42a073a0bdeee7fb1b47221cda222d330d2a","tags":[]},{"url":"https://git.kernel.org/stable/c/ae979c549cba684e67b6c047140f3a8d2439b298","tags":[]},{"url":"https://git.kernel.org/stable/c/f1fc052f2a5890ea6dba80d50254dd6258b13386","tags":[]},{"url":"https://git.kernel.org/stable/c/f606ed93de0c4f1e7e3618779e9fad731455314a","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
