{"id":"CVE-2026-23142","summary":"mm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmm/damon/sysfs-scheme: cleanup access_pattern subdirs on scheme dir setup failure\n\nWhen a DAMOS-scheme DAMON sysfs directory setup fails after setup of\naccess_pattern/ directory, subdirectories of access_pattern/ directory are\nnot cleaned up.  As a result, DAMON sysfs interface is nearly broken until\nthe system reboots, and the memory for the unremoved directory is leaked.\n\nCleanup the directories under such failures.","modified":"2026-04-02T17:30:38.090199921Z","published":"2026-02-14T15:36:08.147Z","related":["SUSE-SU-2026:20838-1","SUSE-SU-2026:20931-1","openSUSE-SU-2026:20416-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23142.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/16236b0b4a08fa3e326cf1373ef789dabdc2e30d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/392b3d9d595f34877dd745b470c711e8ebcd225c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/725d4fdaa01bd1161782081f419e1568cc7432e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ae8ac0066b48ed957bdcab58f0d3543549c57a29"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9711bd0e64812c694a228cf58c9e6032decee54"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/23xxx/CVE-2026-23142.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23142"},{"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":"9bbb820a5bd5f406ae5e0819cc31f2c2e6f4d990"},{"fixed":"ae8ac0066b48ed957bdcab58f0d3543549c57a29"},{"fixed":"e9711bd0e64812c694a228cf58c9e6032decee54"},{"fixed":"16236b0b4a08fa3e326cf1373ef789dabdc2e30d"},{"fixed":"725d4fdaa01bd1161782081f419e1568cc7432e0"},{"fixed":"392b3d9d595f34877dd745b470c711e8ebcd225c"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-23142.json"}}],"schema_version":"1.7.5"}
