kernel: futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock
A flaw was found in the Linux kernel's futex Fast Userspace Mutex requeue mechanism. When a non-top waiter attempts to requeue a Priority Inheritance PI futex it already owns, a NULL pointer dereference can occur. This issue, specifically within the removewaiter function during a self-deadlock...

SUSE CVE-2026-53327
In the Linux kernel, the following vulnerability has been resolved: debugobjects: Do not fillpool if piblockedon On RT enabled kernels, fillpool ends up calling rtlocklock, which asserts if current::piblockedon is set, because a task can obviously only block on one lock as otherwise the priority...
CVE-2026-53327
A flaw was found in the Linux kernel's debugobjects functionality. On systems with Real-Time RT enabled kernels, the fillpool function can lead to a system assertion if a task is already blocked on a lock, causing corruption of the priority inheritance chain. This issue can result in a Denial of...

CVE-2026-53327
Summary: CVE-2026-53327 affects the Linux kernel in the debugobjects path where fill_pool() may interact with rtlock_lock() if current::pi_blocked_on is set on RT-enabled kernels. The connected records confirm concrete remediation across several distributions via patched kernel packages or rootio...
