CVE-2026-98573 net: skbuff: fix pull-bound underflow in skb_checksum_setup_ipv6()

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: fix pull-bound underflow in skbchecksumsetupipv6 skbmaybepulltail subtracts skbheadlenskb from the unsigned max argument and passes the result to pskbpulltail as a signed int. The function does not ensure that max is...

CVE-2026-98572 bpf: Fix immediate JMP JEQ/JNE on MIPS32

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix immediate JMP JEQ/JNE on MIPS32 An addu instruction was emitted instead of addiu, causing the immediate value 1 to be interpreted as register $at. This made the comparison result invalid when the immediate operand was...

CVE-2026-98572

The Linux kernel contains a vulnerability in the bpf subsystem related to MIPS32 architecture. Specifically, the system incorrectly emitted an addu instruction instead of an addiu instruction for immediate JMP JEQ/JNE operations. This caused the immediate value of 1 to be misinterpreted as regist...

CVE-2026-98573

The Linux kernel is vulnerable to an underflow in skb_checksum_setup_ipv6() within the net: skbuff component. The skb_maybe_pull_tail() function fails to ensure that the max argument is at least skb_headlen(skb), leading to a wrap-around to a negative delta when parsing IPv6 extension headers on ...

CVE-2026-98571

The Linux kernel contains a vulnerability in the stmmac driver where buf->page is not cleared after a page is recycled via page_pool_recycle_direct() during a napi_build_skb() failure. This stale pointer causes stmmac_rx_refill() to skip replacement allocation and incorrectly program the alrea...

CVE-2026-98571 net: stmmac: clear stale buf->page after recycling on skb build failure

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: clear stale buf-page after recycling on skb build failure In stmmacrx, when napibuildskb fails the descriptor page is recycled back to the page pool with pagepoolrecycledirect, but buf-page is left pointing at the...

CVE-2026-98570

The Linux kernel contains a vulnerability in the ipv6 networking stack related to how dst_dev_overhead() handles headroom. When seg6 , ioam6 , and rpl lwtunnels request skb_cow_head() space, they may not account for sufficient headroom required by skb_mac_header_rebuild(). Specifically, when proc...

CVE-2026-98570 net: ipv6: keep room for the mac header in dst_dev_overhead()

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: keep room for the mac header in dstdevoverhead The seg6, ioam6 and rpl lwtunnels size their skbcowhead request as the length they are about to push plus dstdevoverhead, then push the new headers and rebuild the mac...

In the Linux kernel, the following vulnerability has been resolved: ipgre: Reject enabling collect metadata through changelink ipgrenetlinkparms can enable collectmd on an existing GRE, GRETAP or ERSPAN device. Unlike newlink, changelink does not enforce metadata tunnel uniqueness. Converting a...

CVE-2026-98569 ip_gre: Reject enabling collect metadata through changelink

In the Linux kernel, the following vulnerability has been resolved: ipgre: Reject enabling collect metadata through changelink ipgrenetlinkparms can enable collectmd on an existing GRE, GRETAP or ERSPAN device. Unlike newlink, changelink does not enforce metadata tunnel uniqueness. Converting a...

CVE-2026-98569

The Linux kernel contains a vulnerability in the ip_gre component where the ipgre_netlink_parms() function can incorrectly enable collect_md on existing GRE, GRETAP, or ERSPAN devices. Because changelink does not enforce metadata tunnel uniqueness, converting a non-metadata device can overwrite t...

CVE-2026-98568 vxlan: use one headroom snapshot for neighbour replies

In the Linux kernel, the following vulnerability has been resolved: vxlan: use one headroom snapshot for neighbour replies vxlannacreate samples LLRESERVEDSPACE to size the reply skb and then samples it again to reserve headroom. A concurrent vxlanchangelink can update neededheadroom between the...

CVE-2026-98568

The Linux kernel contains a Time-of-Check to Time-of-Use (TOCTOU) race condition within the vxlan component. Specifically, the vxlan_na_create() function samples LL_RESERVED_SPACE() twice: once to size the reply skb and again to reserve headroom. A concurrent call to vxlan_changelink() can update...

CVE-2026-98567

The Linux kernel contains a vulnerability where netdev_set_num_tc() lowers dev->num_tc without clearing the dev->tc_to_txq[] or dev->prio_tc_map[] arrays. This allows netdev_txq_to_tc() to return a traffic class value greater than or equal to the new num_tc. When __netif_set_xps_queue() ...
