CVE-2026-74726

CVE-2026-74726 is a race condition in the Linux kernel's bonding driver (ALB mode), specifically in bond_alb_monitor(). The function reads primary_is_promisc under RCU, then drops RCU and acquires RTNL via rtnl_trylock(). In that window the active slave can change (e.g., via RTM_DELLINK), causing...
