CVE-2026-80822

CVE-2026-80822 affects the Linux kernel's mchp-ipc-sbi mailbox driver. The root cause is a missing null check on the return value of devm_kasprintf() in the function mchp_ipc_get_cluster_aggr_irq() . Without this check, a failed allocation could lead to a NULL pointer dereference. The fix adds a ...
