CVE-2026-43249

The CVE-2026-43249 entry describes a race in the Linux kernel 9p/xen frontend: xenwatch and backend change notifications can concurrently call xen_9pfs_front_free, causing a double-free and a general protection fault. The fixes guard the teardown path so only a single caller releases the front-en...

CVE-2026-43196

CVE-2026-43196 affects the Linux kernel PRUSS clock multiplexer path (pruss_clk_mux_setup). The issue is a double free: devm_add_action_or_reset() path frees a resource via pruss_of_free_clk_provider(), which calls of_node_put(clk_mux_np) on error, and a second of_node_put is executed after the p...
