Previously, recovery work could be scheduled even after canceling existing work, potentially leading to use-after-free bugs if recovery accessed freed resources. Rename ivpu_pm_cancel_recovery() to ivpu_pm_disable_recovery() to better reflect its new behavior. The Linux kernel CVE team has assigned CVE-2025-39896 to this issue. Affected and fixed versions =========================== Issue introduced in 6.8 with commit 58cde80f45a2b1683ea3c24a9a9a4b0e1005336b and fixed in 6.12.46 with commit 54c49eca38dbd06913a696f6d7610937dcfad226 Issue introduced in 6.8 with commit 58cde80f45a2b1683ea3c24a9a9a4b0e1005336b and fixed in 6.16.6 with commit 565d2c15b6c36c3250e694f7b9a86229c1787be5 Issue introduced in 6.8 with commit 58cde80f45a2b1683ea3c24a9a9a4b0e1005336b and fixed in 6.17 with commit 69a79ada8eb034ce016b5b78fb7d08d8687223de 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-2025-39896 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/accel/ivpu/ivpu_drv.c drivers/accel/ivpu/ivpu_pm.c drivers/accel/ivpu/ivpu_pm.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/54c49eca38dbd06913a696f6d7610937dcfad226 https://git.kernel.org/stable/c/565d2c15b6c36c3250e694f7b9a86229c1787be5 https://git.kernel.org/stable/c/69a79ada8eb034ce016b5b78fb7d08d8687223de
