This offloads the processing off the work from the irq into a workqueue. The Linux kernel CVE team has assigned CVE-2024-26719 to this issue. Affected and fixed versions =========================== Fixed in 6.6.18 with commit cc0037fa592d Fixed in 6.7.6 with commit 985d053f7633 Fixed in 6.8 with commit 39126abc5e20 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-2024-26719 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: drivers/gpu/drm/nouveau/nouveau_fence.c drivers/gpu/drm/nouveau/nouveau_fence.h 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/cc0037fa592d56e4abb9c7d1c52c4d2dc25cd906 https://git.kernel.org/stable/c/985d053f7633d8b539ab1531738d538efac678a9 https://git.kernel.org/stable/c/39126abc5e20611579602f03b66627d7cd1422f0
