In the Linux kernel, the following vulnerability has been resolved: packet: synchronize pressure clearing with ring reconfiguration packetsetring updates the RX ring state under skreceivequeue.lock, but used to publish the tpacket receive mode through po-prothook.func after releasing that lock...

CVE-2026-74663 net/sched: reject overly deep qdisc hierarchies

In the Linux kernel, the following vulnerability has been resolved: net/sched: reject overly deep qdisc hierarchies Deep qdisc hierarchies can lead to excessive recursion in qdisc tree walkers and exhaust the kernel stack. The existing loop check does not cover the create-and-graft path, so a...

CVE-2026-74663

CVE-2026-74663 affects the Linux kernel in the net/sched subsystem. Deep queueing discipline (qdisc) hierarchies can cause excessive recursion in qdisc tree walkers, exhausting the kernel stack and leading to a Denial of Service via system crash. The existing loop check does not cover the create-...

CVE-2026-74658

CVE-2026-74658 is a race condition in the Linux kernel robust futex exit handling. When a woken waiter is killed before it can acquire the futex or re-arm FUTEX_WAITERS , and a third task re-acquires the futex via the uncontended fast path, the notification is lost. The new owner sees no FUTEX_WA...

CVE-2026-74657

CVE-2026-74657 affects the Linux kernel IPv4 FIB netlink size calculation. The function fib_nlmsg_size() incorrectly estimates nexthop space by assuming all gateways are encoded as IPv4 RTA_GATEWAY attributes. However, IPv4 routes can carry IPv6 gateways , which are dumped as RTA_VIA by fib_nexth...
