If the damon_ctx allocation was failed,\ntherefore, code execution reaches to damon_commit_ctx() while 'ctx' is\nNULL.  As a result, it dereferences the NULL 'ctx' pointer.  Avoid the\nNULL dereference by returning -ENOMEM if 'ctx' is NULL.","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-476"],"references":["https://git.kernel.org/stable/c/6d48f15659395bf1381114f01be91bc68e0be46a","https://git.kernel.org/stable/c/ab04340b5ae5d52c1d46b750538febcde9d889e7","https://git.kernel.org/stable/c/daab1996431a71f43219dcac48ecc9ad2aad3f1c"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-53335","score":0.0017,"percentile":0.0634,"date":"2026-10-31"},"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).
