In the Linux kernel, the following vulnerability has been resolved: batman-adv: bypass empty buckets in batadvpurgeorigref Many syzbot reports are pointing to soft lockups in batadvpurgeorigref 1 Root cause is unknown, but we can avoid spending too much time there and perhaps get more interesting...

kernel: xhci: handle isoc Babble and Buffer Overrun events properly

A flaw was found in the Linux kernel related to the Extensible Host Controller Interface xHCI subsystem, specifically how it handles certain events. The issue arises when the xHCI driver improperly handles isochronous isoc Babble and Buffer Overrun events. The vulnerability occurs because the xHC...

kernel: wifi: brcm80211: handle pmk_op allocation failure

A vulnerability was found in the Linux kernel's Wi-Fi cfg80211.c driver, where a lack of proper checks can result in a NULL pointer dereference.
