If\nthis inconsistent behavior is not due to a previously fixed bug, then an\nunexpected race is occurring, so return a temporary error -EAGAIN instead.\n\nThis prevents callers such as __block_write_begin_int() from requesting a\nread into a buffer that is not mapped, which would cause the BUG_ON check\nfor the BH_Mapped flag in submit_bh_wbc() to fail.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":[],"references":["https://git.kernel.org/stable/c/0c8aa4cfda4e4adb15d5b6536d155eca9c9cd44c","https://git.kernel.org/stable/c/192e9f9078c96be30b31c4b44d6294b24520fce5","https://git.kernel.org/stable/c/269cdf353b5bdd15f1a079671b0f889113865f20","https://git.kernel.org/stable/c/32eaee72e96590a75445c8a6c7c1057673b47e07","https://git.kernel.org/stable/c/48d443d200237782dc82e6b60663ec414ef02e39"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T21:49:08.435428910+00:00"},"epss":{"cve":"CVE-2024-26955","score":0.00255,"percentile":0.17199,"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).
