If the buffer is smaller than the data size, return only the portion that fits instead of failing. The Linux kernel CVE team has assigned CVE-2026-74419 to this issue. Affected and fixed versions =========================== Issue introduced in 6.14 with commit 850d71f6bf4c2010efae845f9ff841cce902f22c and fixed in 7.1.5 with commit 097e57195ef813735c8b714d6503bf3ad0742515 Issue introduced in 6.14 with commit 850d71f6bf4c2010efae845f9ff841cce902f22c and fixed in 7.2-rc1 with commit 6e87001fe19f251e2ae14373bc76554358a13df2 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-2026-74419 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/amdxdna/aie2_error.c drivers/accel/amdxdna/aie2_message.c drivers/accel/amdxdna/aie2_pci.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/097e57195ef813735c8b714d6503bf3ad0742515 https://git.kernel.org/stable/c/6e87001fe19f251e2ae14373bc76554358a13df2
