SUSE CVE-2026-43010

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject sleepable kprobemulti programs at attach time kprobe.multi programs run in atomic/RCU context and cannot sleep. However, bpfkprobemultilinkattach did not validate whether the program being attached had the sleepable...

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...
