CVE-2026-53275 ipv6: mcast: Fix use-after-free when processing MLD queries

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: Fix use-after-free when processing MLD queries When processing an MLD query, a pointer to the multicast group address is retrieved when initially parsing the packet. This pointer is later dereferenced without being...

CVE-2026-53276

The CVE-2026-53276 entry concerns the Linux kernel Bluetooth ISO stack. A use-after-free occurs in iso_sock_rebind_bc where the bis pointer is cached and the socket lock is released before traversals, allowing a concurrent close() to free the hci_conn and its bis structure. The code then accesses...
