CVE-2026-68187 exec: fix unsigned loop counter wrap in transfer_args_to_stack()

In the Linux kernel, the following vulnerability has been resolved: exec: fix unsigned loop counter wrap in transferargstostack The stop value is derived from bprm-p PAGESHIFT. The index variable is an unsigned long. If bprm-p drops below PAGESIZE and stop becomes zero the loop condition index =...

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...

FreeBSD -- Local privilege escalation via execve(2) TOCTOU race

Problem Description: During execve2 of a SUID binary, the new virtual address space is installed before the process credentials are updated. During this window, a process running as the same user can access the target process's memory via procfs or linprocfs, because the kernel's debugging...

CVE-2026-49414 ASLR bypass for setuid executables via procctl(2)

The ELF image activator cleared per-process ASLR preference flags for setuid binaries after the code that computes the PIE base address, rather than before. As a result, a user-requested ASLR disable was still in effect at the point where the base address was chosen. An unprivileged local user ca...

FreeBSD Security Advisory - FreeBSD-SA-26:30.linux

FreeBSD Security Advisory - The Linuxulator determined whether a binary was set-user-ID or set-group-ID by checking the PSUGID process flag. During execve2, this flag is not yet set at the point where the auxiliary vector is constructed, so ATSECURE was incorrectly set to zero for set-user-ID and...
