CVE-2026-89766

This Linux kernel vulnerability affects the PIDFD_GET_*_NAMESPACE ioctls in pidfd_ioctl(), which perform a ptrace credentials check before handing out a namespace file descriptor. Unlike the equivalent procfs paths (proc_ns_get_link, proc_ns_readlink), the pidfd path did not hold the target task'...

CVE-2026-89765 timers/itimer: Zero-init old itimerval before copy to userspace

In the Linux kernel, the following vulnerability has been resolved: timers/itimer: Zero-init old itimerval before copy to userspace On native sparc64, struct kerneloldtimeval contains a four-byte hole after tvusec because tvsec is 64-bit while kernelsusecondst is 32-bit. putitimerval fills only t...

CVE-2026-89765

CVE-2026-89765 is a Linux kernel information disclosure vulnerability in the timers/itimer subsystem. On native sparc64 , the __kernel_old_timeval struct contains a four-byte alignment hole after tv_usec (because tv_sec is 64-bit while __kernel_suseconds_t is 32-bit). The put_itimerval() function...

CVE-2026-89764

CVE-2026-89764 affects the Linux kernel's Rust devres (device resource) subsystem. A race condition occurs when two code paths concurrently revoke a Devres resource: the driver core's devres_release_all() calls Revocable::revoke() via the release callback, while Devres::drop() calls revoke_nosync...
