If an error occurs, writeback_iter() needs to be called again with *error set to the error so that it can clean up iteration state. Further, the current folio needs unlocking and redirtying. The Linux kernel CVE team has assigned CVE-2026-72364 to this issue. Affected and fixed versions =========================== Issue introduced in 6.10 with commit 288ace2f57c9d06dd2e42bd80d03747d879a4068 and fixed in 6.12.97 with commit fb39ffd3cc5422887fd118668ff45ebfdbc83302 Issue introduced in 6.10 with commit 288ace2f57c9d06dd2e42bd80d03747d879a4068 and fixed in 6.18.40 with commit 1bb33d959aabcde07d724b5eb9992462e91fa79a Issue introduced in 6.10 with commit 288ace2f57c9d06dd2e42bd80d03747d879a4068 and fixed in 7.1.5 with commit 89df9c158a25d0a7c6ca079a9bd9ca7009d75c7b Issue introduced in 6.10 with commit 288ace2f57c9d06dd2e42bd80d03747d879a4068 and fixed in 7.2-rc2 with commit ac5f95ac5d6d0f4c567b8b642825705a2bf0d79e Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-72364 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: fs/netfs/write_issue.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/fb39ffd3cc5422887fd118668ff45ebfdbc83302 https://git.kernel.org/stable/c/1bb33d959aabcde07d724b5eb9992462e91fa79a https://git.kernel.org/stable/c/89df9c158a25d0a7c6ca079a9bd9ca7009d75c7b https://git.kernel.org/stable/c/ac5f95ac5d6d0f4c567b8b642825705a2bf0d79e
