So put a lock on the path in order to\nserialize the accesses to prevent the ability for this to be called at\ntoo high of a frequency and saturate the machine.","modified":"2026-03-20T12:35:02.423570Z","published":"2024-02-24T14:56:56.992Z","related":["ALSA-2024:2394","SUSE-SU-2024:0855-1","SUSE-SU-2024:0856-1","SUSE-SU-2024:0857-1","SUSE-SU-2024:0858-1","SUSE-SU-2024:0900-1","SUSE-SU-2024:0900-2","SUSE-SU-2024:0910-1","SUSE-SU-2024:0926-1","SUSE-SU-2024:0977-1","SUSE-SU-2024:1466-1","SUSE-SU-2024:1480-1","SUSE-SU-2024:1490-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26602.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2441a64070b85c14eecc3728cc87e883f953f265"},{"type":"WEB","url":"https://git.kernel.org/stable/c/24ec7504a08a67247fbe798d1de995208a8c128a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3cd139875e9a7688b3fc715264032620812a5fa3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/50fb4e17df319bb33be6f14e2a856950c1577dee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/944d5fe50f3f03daacfea16300e656a1691c4a23"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b6a2a9cbb67545c825ec95f06adb7ff300a2ad71"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c5b2063c65d05e79fad8029324581d86cfba7eea"},{"type":"WEB","url":"https://git.kernel.org/stable/c/db896bbe4a9c67cee377e5f6a743350d3ae4acf6"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/06/msg00020.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26602.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26602"},{"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":"22e4ebb975822833b083533035233d128b30e98f"},{"fixed":"3cd139875e9a7688b3fc715264032620812a5fa3"},{"fixed":"2441a64070b85c14eecc3728cc87e883f953f265"},{"fixed":"db896bbe4a9c67cee377e5f6a743350d3ae4acf6"},{"fixed":"50fb4e17df319bb33be6f14e2a856950c1577dee"},{"fixed":"24ec7504a08a67247fbe798d1de995208a8c128a"},{"fixed":"b6a2a9cbb67545c825ec95f06adb7ff300a2ad71"},{"fixed":"c5b2063c65d05e79fad8029324581d86cfba7eea"},{"fixed":"944d5fe50f3f03daacfea16300e656a1691c4a23"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-26602.json"}}],"schema_version":"1.7.5"}
