This issue occurred when the creation of reply or request queues failed, and the driver freed the memory first, but attempted to mem set the content of the freed memory, leading to a system crash. Add NULL pointer checks for reply and request queues before accessing the reply/request memory during cleanup The Linux kernel CVE team has assigned CVE-2026-43473 to this issue. Affected and fixed versions =========================== Fixed in 5.15.203 with commit f8e833572a3e12a2a1ffe7b3646af024264d38ca Fixed in 6.1.167 with commit 7df0296ad4e9253d12c6dbe7f120044dddc95600 Fixed in 6.6.130 with commit 7da755e0d02e9ca035065127e108d1fed8950dc8 Fixed in 6.12.78 with commit 78d3f201f8b609928eade53cf03a52df5415aaf7 Fixed in 6.18.19 with commit e978a36f332ede78eb4de037b517db16265d420d Fixed in 6.19.9 with commit 220d7ca70611a73d50ef8e9edac630ed1ececb7c Fixed in 7.0 with commit fa96392ebebc8fade2b878acb14cce0f71016503 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.

Affected files ============== The file(s) affected by this issue are: drivers/scsi/mpi3mr/mpi3mr_fw.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/f8e833572a3e12a2a1ffe7b3646af024264d38ca https://git.kernel.org/stable/c/7df0296ad4e9253d12c6dbe7f120044dddc95600 https://git.kernel.org/stable/c/7da755e0d02e9ca035065127e108d1fed8950dc8 https://git.kernel.org/stable/c/78d3f201f8b609928eade53cf03a52df5415aaf7 https://git.kernel.org/stable/c/e978a36f332ede78eb4de037b517db16265d420d https://git.kernel.org/stable/c/220d7ca70611a73d50ef8e9edac630ed1ececb7c https://git.kernel.org/stable/c/fa96392ebebc8fade2b878acb14cce0f71016503
