CVE-2026-53358 Bluetooth: L2CAP: use chan timer to close channels in cleanup_listen()

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: use chan timer to close channels in cleanuplisten l2capchanclose removes the channel from conn-chanl, which must be done under conn-lock. cleanuplisten runs under the parent sklock, so acquiring conn-lock would...

CVE-2026-53358

The CVE-2026-53358 entry describes a Linux kernel Bluetooth L2CAP use of a timer-based close to avoid lock-order inversion, replacing a direct l2cap_chan_close() call with l2cap_chan_timeout() for asynchronous cleanup. The root cause is an incorrect conflate of conn->lock, chan->lock, and s...

PT-2026-55234

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the Bluetooth L2CAP socket cleanup process. The problem occurs during a race condition between l2cap sock cleanup listen and l2cap conn del. Specifically...

PT-2026-55235

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the Bluetooth L2CAP implementation where calling l2cap chan close within cleanup listen causes a lock inversion. Specifically, cleanup listen operates under the parent...

kernel: ALSA: aloop: Fix peer runtime UAF during format-change stop

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture aloop driver. This Use-After-Free UAF vulnerability occurs when loopbackcheckformat stops the capture side during a format change, while a concurrent close operation detaches or frees the runtime. An attacker could...

CVE-2026-54897

Oj (Optimized JSON) Ruby gem versions prior to 3.17.2 contain a heap use-after-free in Oj::Doc iterators (each_value, each_child, each_leaf). If a Ruby block yields during iteration and doc.close or d.close is called, the heap memory is freed while the C iterator is active, leading to a use-after...

CVE-2026-54897 Oj : Use-After-Free in Oj::Doc Iterators via Reentrant Close

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. Prior to 3.17.2, Oj::Doc iterators eachvalue, eachchild, eachleaf were vulnerable to a heap use-after-free. When a Ruby block yielded during iteration calls doc.close or d.close, the document's heap memory is freed...
