kernel: seccomp: passthrough uretprobe systemcall without filtering

A flaw was found in the Linux kernel. This vulnerability occurs when uretprobes, a debugging feature that monitors function returns in user-space programs, are used. The kernel's seccomp secure computing mode mechanism, which restricts system calls a program can make, incorrectly blocks the...

CVE-2026-61711

A flaw was found in BuildKit. A custom frontend could craft a build request with an invalid security mode, leading to the disabling of Seccomp and AppArmor protections for the build container. This bypasses the intended sandbox mechanisms, potentially allowing for broader impact within the...
