CVE-2026-43010

A flaw was found in the Linux kernel. A local user could attach a sleepable BPF kprobemulti program, which allows sleepable helper functions, such as bpfcopyfromuser, to be invoked from a non-sleepable context. This incorrect handling can lead to a system crash, resulting in a Denial of Service D...
