CVE-2026-74751

CVE-2026-74751 is a bug in the Linux kernel's RISC-V ZBB-optimized strnlen function. The loop loads one word ahead of the aligned boundary before performing the boundary check. When the string pointer is aligned and the count is a multiple of the word size, the loop can read a full word at exactl...

CVE-2026-74750 ovpn: defer key slot crypto freeing to workqueue

In the Linux kernel, the following vulnerability has been resolved: ovpn: defer key slot crypto freeing to workqueue Key slots are released through a kref and the existing release path frees the AEAD transforms from an RCU callback. That is not safe for all crypto implementations: cryptofreeaead...

CVE-2026-74748 netfilter: ipset: fix refcount race between list:set GC and swap

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: fix refcount race between list:set GC and swap ipsetputbyindex resolved the index to a set pointer under RCU, then took ipsetreflock in ipsetput to decrement set-ref. ipsetswap holds that same lock while swappin...

CVE-2026-74749

CVE-2026-74749 affects the Linux kernel 's rseq (restricted sequence) subsystem. When __exit_to_user_mode_loop() invokes rseq_grant_timeslice_extension() with interrupts enabled, a granted time slice extension calls hrtimer_rearm_deferred_tif(), which in turn calls __hrtimer_rearm_deferred() — a ...

CVE-2026-74748

CVE-2026-74748 is a refcount race in the Linux kernel's netfilter ipset subsystem. The function __ip_set_put_byindex() resolves a set index under RCU but decrements the reference count only after acquiring ip_set_ref_lock. A concurrent ip_set_swap() call can interleave between these two steps, ca...

CVE-2026-74747

CVE-2026-74747 affects the Linux kernel in the ipvs (IP Virtual Server) subsystem, specifically in ip_vs_nat_icmp() . After reading embedded IP headers from skb frags, the ihl field is not revalidated; a local process can modify it so that after skb_ensure_writable() a larger value is visible, ca...

CVE-2026-74746

CVE-2026-74746 is a slab-use-after-free vulnerability in the Linux kernel netfilter flowtable subsystem. The root cause lies in nf_flow_table_iterate(), which treats only original-direction tuple nodes as owning entries. When the original node is published first, the garbage collector can observe...
