CVE-2026-72126

The CVE concerns a Linux kernel race in the isotp path of CAN networking. The fix makes isotp_release() always call synchronize_rcu() before cancelling RX timers, regardless of so->bound, addressing a scenario where NETDEV_UNREGISTER could allow a use-after-free of a timer callback if an in-fl...

CVE-2026-72120

CVE-2026-72120 affects the Linux kernel bcm subsystem. The issue stems from missing RCU list annotations/operations for bcm_op handling, leading to improper initialization when traversing bcm_op under rcu_read_lock(). Fixes include moving list_add_rcu() calls to the end of bcm_[rx|tx]_setup and U...
