GHSA-P6RV-2QPM-FWVG kill: 'kill -1' parsed as PID -1, sending SIGTERM to all processes (system crash / DoS)

kill -1 is incorrectly parsed as a positional pid = -1; combined with the default SIGTERM this calls kill-1, SIGTERM, signaling nearly every process the caller can see. GNU kill recognizes -1/-9 as signals and reports "not enough arguments". $ kill -1 uutils: kill-1, SIGTERM - mass termination /...

PYSEC-2026-952 Incomplete validation in signal ops leads to crashes in TensorFlow

Impact The tf.compat.v1.signal.rfft2d and tf.compat.v1.signal.rfft3d lack input validation and under certain condition can result in crashes due to CHECK-failures. Patches We have patched the issue in GitHub commit 0a8a781e597b18ead006d19b7d23d0a369e9ad73 merging GitHub PR 55274. The fix will be...

CVE-2026-53352

A flaw was found in the Linux kernel. A race condition exists in the zapotherthreads function where job control flags are not properly cleared for the calling thread. This can occur when a multi-threaded process receives a stop signal, and one of its threads concurrently calls execve. The...

CVE-2026-53352

CVE-2026-53352 affects the Linux kernel and stems from a race in zap_other_threads() where the calling thread’s JOBCTL_PENDING_MASK is not cleared during thread-group destruction. When a multi-threaded process is stopped (SIGSTOP) and one thread execs, zap_other_threads() can abort the group-stop...

CVE-2026-45259

sigqueue2 was marked as permitted in capability mode with the introduction of Capsicum in 2011, but the implementation of kernsigqueue did not include a capability mode check restricting signal delivery to the calling process's own PID. A process in capability mode can use sigqueue2 to send signa...

CVE-2026-45259

CVE-2026-45259 affects FreeBSD where sigqueue(2) was allowed in capability mode but kern_sigqueue lacked a capability-mode check to restrict signal delivery to the caller’s own PID. The issue enables a capability-mode sandboxed process to signal other processes (including SIGKILL/SIGSTOP) within ...
