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-2026-72073

CVE-2026-72073 concerns the Linux kernel mmc/vub300 driver. The vulnerability arises from a use-after-free race on probe failure: the inactivity timer can be armed before mmc_add_host() completes, and if add_host() fails, a timer/deadwork path may still hold a kref, leading to the vub300 storage ...
