In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: publish HWDEAD after worker is done flowoffloadworkdel sets NFFLOWHWDEAD before the work handler clears NFFLOWHWPENDING. Once a flow is both HWDYING and HWDEAD, a concurrent garbage collection pass can remov...

CVE-2026-98625

The Linux kernel contains a use-after-free vulnerability within the netfilter flowtable component. The issue resides in flow_offload_work_del(), which incorrectly sets the NF_FLOW_HW_DEAD bit before clearing the NF_FLOW_HW_PENDING bit. Because the offload worker lacks an RCU read lock or a flow r...

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlinkqueue: hold nfnl mutex in event notifier We must serialize the release notifier and the config netlink function. A concurrent thread can issue close which can call the release function while unrelated socket...

CVE-2026-98624

A vulnerability exists in the Linux kernel 's netfilter: nfnetlink_queue component where a concurrent thread issuing a close() call can trigger the release function while unrelated socket processes request an UNBIND for the same portid. This race condition leads to a general protection fault (Oop...

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/clk: fix list cursor use after loop in nvkmclkustateupdate If listforeachentry exits without hitting a break then "pstate" is not a valid pstate pointer. Introduce a "found" variable instead. The check is reachable fr...

CVE-2026-98623 drm/nouveau/clk: fix list cursor use after loop in nvkm_clk_ustate_update

In the Linux kernel, the following vulnerability has been resolved: drm/nouveau/clk: fix list cursor use after loop in nvkmclkustateupdate If listforeachentry exits without hitting a break then "pstate" is not a valid pstate pointer. Introduce a "found" variable instead. The check is reachable fr...

CVE-2026-98623

The Linux kernel contains a vulnerability in the drm/nouveau/clk component within the nvkm_clk_ustate_update function. The root cause is a use-after-loop error where the code fails to validate if a pointer is valid after a list_for_each_entry() loop completes without hitting a break. This allows ...

EUVD-2026-103667

In the Linux kernel, the following vulnerability has been resolved: net/sched: actct: don't WARN on benign flowoffloadalloc failure flowoffloadalloc returns NULL when the conntrack entry is dying e.g. raced with a conntrack flush or when the GFPATOMIC allocation fails; both are expected under loa...

CVE-2026-98622

The Linux kernel contains a flaw in the net/sched: act_ct component where the flow_offload_alloc() function triggers a kernel warning upon failure. These failures occur during benign scenarios, such as when a conntrack entry is dying (e.g., during a raced conntrack flush) or when GFP_ATOMIC alloc...

CVE-2026-98622 net/sched: act_ct: don't WARN on benign flow_offload_alloc() failure

In the Linux kernel, the following vulnerability has been resolved: net/sched: actct: don't WARN on benign flowoffloadalloc failure flowoffloadalloc returns NULL when the conntrack entry is dying e.g. raced with a conntrack flush or when the GFPATOMIC allocation fails; both are expected under loa...

EUVD-2026-103666

In the Linux kernel, the following vulnerability has been resolved: net: gue: reject invalid REMCSUM offsets The REMCSUM option carries an absolute checksum start and checksum field offset. gueremcsum passes them to skbremcsumprocess, whose partial path stores offset - start in the u16...

CVE-2026-98621 net: gue: reject invalid REMCSUM offsets

In the Linux kernel, the following vulnerability has been resolved: net: gue: reject invalid REMCSUM offsets The REMCSUM option carries an absolute checksum start and checksum field offset. gueremcsum passes them to skbremcsumprocess, whose partial path stores offset - start in the u16...

CVE-2026-98621

The Linux kernel contains a vulnerability where the REMCSUM option can cause an integer underflow . The gue_remcsum() function passes an absolute checksum start and field offset to skb_remcsum_process(), which calculates the difference and stores it in a u16 variable. If the offset is less than t...

EUVD-2026-103665

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtkethsoc: unregister netdevices in case of probe failure If registernetdev fails for one of the MTKMAXDEVS devices in mtkprobe, the error path jumps to errdeinitppe, skipping mtkunregdev. The previously registered...

CVE-2026-98620 net: ethernet: mtk_eth_soc: unregister net_devices in case of probe failure

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: mtkethsoc: unregister netdevices in case of probe failure If registernetdev fails for one of the MTKMAXDEVS devices in mtkprobe, the error path jumps to errdeinitppe, skipping mtkunregdev. The previously registered...

CVE-2026-98620

The Linux kernel contains a vulnerability in the mtk_eth_soc ethernet driver. If register_netdev() fails for one of the devices in mtk_probe() , the error path skips the necessary mtk_unreg_dev() call. This causes previously registered devices to be freed by mtk_free_dev() while still in the NETR...
