The abandonment process expects\nthe 'subreq' variable to be set to the place to start abandonment from, but\nit doesn't always have a useful value (it will be uninitialised on the\nfirst pass through the loop and it may point to a deleted subrequest on\nlater passes).\n\nFix the first jump to \"abandon:\" to set subreq to the start of the first\nsubrequest expected to need retry (which, in this abandonment case, turned\nout unexpectedly to no longer have NEED_RETRY set).\n\nAlso clear the subreq pointer after discarding superfluous retryable\nsubrequests to cause an oops if we do try to access it.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-125","CWE-457"],"references":["https://git.kernel.org/stable/c/3e5fd8f53b575ff2188f82071da19c977ca56c41","https://git.kernel.org/stable/c/7e57523490cd2efb52b1ea97f2e0a74c0fb634cd","https://git.kernel.org/stable/c/8f2f2bd128a8d9edbc1e785760da54ada3df69b7"],"products":["linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-21T03:43:09.190223697+00:00"},"epss":{"cve":"CVE-2026-31435","score":0.00342,"percentile":0.27502,"date":"2026-10-25"},"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).
