In the Linux kernel, the following vulnerability has been resolved: net/smc: fix UAF on lgr list traversal in smcrporterr smcrporterr traverses smclgrlist.list without holding smclgrlist.lock, allowing a concurrent smclgrterminatesched to free an lgr while it is still being dereferenced. Hold...

CVE-2026-98559

The Linux kernel contains a Use-After-Free (UAF) vulnerability in the net/smc component. The issue exists because the smcr_port_err() function traverses smc_lgr_list.list without acquiring the smc_lgr_list.lock , which allows a concurrent call to smc_lgr_terminate_sched() to free an lgr object wh...

CVE-2026-98559 net/smc: fix UAF on lgr list traversal in smcr_port_err()

In the Linux kernel, the following vulnerability has been resolved: net/smc: fix UAF on lgr list traversal in smcrporterr smcrporterr traverses smclgrlist.list without holding smclgrlist.lock, allowing a concurrent smclgrterminatesched to free an lgr while it is still being dereferenced. Hold...

CVE-2026-98558

The Linux kernel contains a vulnerability where the dev_cpu_dead() function fails to flush net_hotdata.skb_defer_nodes when a CPU goes offline. This causes pending skbs to remain stranded if the offline CPU held them, potentially leading to an indefinite stall in page_pool_destroy() during networ...

CVE-2026-98558 net: flush skb_defer_nodes in dev_cpu_dead()

In the Linux kernel, the following vulnerability has been resolved: net: flush skbdefernodes in devcpudead When a CPU goes offline, devcpudead drains its softnet queues completionqueue, outputqueue, polllist, processqueue, and inputpktqueue, but leaves nethotdata.skbdefernodes untouched. If oldcp...

EUVD-2026-103602

In the Linux kernel, the following vulnerability has been resolved: gve: DQO: fix header length used by gvecansendtso for UDP GSO gvecansendtso computes how many buffers each segment of a GSO packet would span, and for this it needs the length of the headers that the device replicates in front of...

CVE-2026-98557

The Linux kernel contains a vulnerability in the gve driver regarding UDP GSO packet handling. The function gve_can_send_tso() incorrectly uses skb_tcp_all_headers(), which reads the TCP header's doff field. For SKB_GSO_UDP_L4 packets (which lack a TCP header), this causes tcp_hdrlen() to read an...

CVE-2026-98557 gve: DQO: fix header length used by gve_can_send_tso() for UDP GSO

In the Linux kernel, the following vulnerability has been resolved: gve: DQO: fix header length used by gvecansendtso for UDP GSO gvecansendtso computes how many buffers each segment of a GSO packet would span, and for this it needs the length of the headers that the device replicates in front of...

CVE-2026-98556

The Linux kernel contains a vulnerability in the gve driver where TSO (TCP Segmentation Offload) packets with an out-of-range MSS (Maximum Segment Size) are not properly rejected. The gve_prep_tso() function fails to enforce the required limit of

EUVD-2026-103601

In the Linux kernel, the following vulnerability has been resolved: gve: DQO: reject TSO packets with an out of range MSS gvepreptso notes that the device requires the MSS to be len and gsosegs, never gsosize. Such a packet reaches gvetxfilltsoctxdesc, which puts gsosize into the mss field of the...

CVE-2026-98556 gve: DQO: reject TSO packets with an out of range MSS

In the Linux kernel, the following vulnerability has been resolved: gve: DQO: reject TSO packets with an out of range MSS gvepreptso notes that the device requires the MSS to be len and gsosegs, never gsosize. Such a packet reaches gvetxfilltsoctxdesc, which puts gsosize into the mss field of the...

CVE-2026-98555

A vulnerability exists in the Linux kernel 's LLC (Light Link Control) component. Specifically, when the llc_mac_hdr_init() function fails within llc_conn_ac_resend_i_xxx_x_set_0_or_send_rr() , the system calls kfree_skb(skb) instead of kfree_skb(nskb) . This oversight causes a memory leak of the...

CVE-2026-98555 llc: fix skb UAF and leaks on llc_mac_hdr_init() failure

In the Linux kernel, the following vulnerability has been resolved: llc: fix skb UAF and leaks on llcmachdrinit failure In llcconnacresendixxxxset0orsendrr, if llcmachdrinit fails, kfreeskbskb is called instead of kfreeskbnskb. This leaks the newly allocated nskb, reads from the freed skb via...

CVE-2026-98554 vlan: ensure sufficient headroom in vlan_dev_hard_header()

In the Linux kernel, the following vulnerability has been resolved: vlan: ensure sufficient headroom in vlandevhardheader Callers that only reserve ETHHLEN or less such as llcallocframe, or skbs allocated before dynamic device/headroom changes e.g. toggling VLANFLAGREORDERHDR or bonding/team...

CVE-2026-98554

The Linux kernel contains a vulnerability in the vlan component where certain callers (e.g., llc_alloc_frame() ) or skbs allocated before dynamic headroom changes can reach vlan_dev_hard_header() with insufficient headroom. This condition triggers a skb_under_panic() . The issue is addressed by u...
