CVE-2026-53259

CVE-2026-53259 (Linux kernel) fixes a race in IPv6 anycast address management. The root cause was a window where inserting an aca into the global inet6_acaddr_lst[] and its hash could be separated from the teardown path (RTNL), causing the ac_addr to be freed while still linked, i.e., a slab-use-...

CVE-2026-53231

CVE-2026-53231 (Linux kernel) : The issue affects the PHY subsystem where PHY-driven SFP cages are not supported with the genphy code. Investigations show that sfp_bus_add_upstream() for genphy can deadlock because PHY probing runs under RTNL for genphy while non-genphy drivers do not. The root c...
