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

In the Linux kernel, the following vulnerability has been resolved: signal: clear JOBCTLPENDINGMASK for caller in zapotherthreads When a multi-threaded process receives a stop signal e.g., SIGSTOP, dosignalstop sets JOBCTLSTOPPENDING and JOBCTLSTOPCONSUME on all threads and sets...

CVE-2026-53352

Summary: CVE-2026-53352 affects the Linux kernel’s thread-stop handling. When a multi-threaded process receives a stop signal, do_signal_stop() sets JOBCTL_STOP_PENDING and JOBCTL_STOP_CONSUME on all threads and tracks group_stop_count. If one thread concurrently execs, zap_other_threads() kills ...

CVE-2026-53352 signal: clear JOBCTL_PENDING_MASK for caller in zap_other_threads()

In the Linux kernel, the following vulnerability has been resolved: signal: clear JOBCTLPENDINGMASK for caller in zapotherthreads When a multi-threaded process receives a stop signal e.g., SIGSTOP, dosignalstop sets JOBCTLSTOPPENDING and JOBCTLSTOPCONSUME on all threads and sets...

kernel: perf_event_open() and execve() race in setuid programs allows a data leak

A race condition in perfeventopen allows local attackers to leak sensitive data from setuid programs. As no relevant locks in particular the credguardmutex are held during the ptracemayaccess call, it is possible for the specified target task to perform an execve syscall with setuid execution...

kernel: race condition between chown() and execve()

A race condition flaw was found between the chown and execve system calls. When changing the owner of a setuid user binary to root, the race condition could momentarily make the binary setuid root. A local, unprivileged user could potentially use this flaw to escalate their privileges on the syst...

USN-2598-2 linux vulnerability

USN-2598-1 fixed vulnerabilities in the Linux kernel, however an unrelated regression in the auditing of some path names was introduced. Due to the regression the system could crash under certain conditions. This update fixes the problem. We apologize for the inconvenience. Original advisory...
