Fix those.\n\nNote that only DAMON sysfs interface users are affected.  Other DAMON core\nAPI user modules that more focused more on simple and dedicated production\nusages, including DAMON_RECLAIM and DAMON_LRU_SORT are not using the buggy\nfunction in the way, so not affected.\n\n\nThis patch (of 2):\n\nWhen new DAMON targets are added via damon_commit_targets(), the newly\ncreated targets are not deallocated when updating the internal data\n(damon_commit_target()) is failed.  Worse yet, even if the setup is\nsuccessfully done, the new target is not linked to the context.  Hence,\nthe new targets are always leaked regardless of the internal data setup\nfailure.  Fix the leaks.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-401"],"references":["https://git.kernel.org/stable/c/3647932d0b3e609c762c55e8f9fe10a09776e0a7","https://git.kernel.org/stable/c/8debfc5b1aa569d3d2ac836af2553da037611c61"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:58:20.756570362+00:00"},"epss":{"cve":"CVE-2024-57886","score":0.00177,"percentile":0.07271,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
