CVE-2026-72126

In the Linux kernel, the following vulnerability has been resolved: can: isotp: use unconditional synchronizercu in isotprelease isotpnotify unregisters the RCU CAN filters via canrxunregister and clears so-bound without waiting for a grace period. isotprelease uses so-bound to decide whether it...

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...
