CVE-2026-98306

The Linux kernel contains a vulnerability where the IPSKB_L3SLAVE flag is not set during IPIP decapsulation , despite being set for IPv6. Specifically, while vrf_ip6_rcv() sets IP6SKB_L3SLAVE in the IPv6 control block, decap_and_validate() fails to set IPSKB_L3SLAVE in the IPv4 control block. Thi...

CVE-2026-98306 seg6: set IPSKB_L3SLAVE from IP6SKB_L3SLAVE on IPIP decapsulation

In the Linux kernel, the following vulnerability has been resolved: seg6: set IPSKBL3SLAVE from IP6SKBL3SLAVE on IPIP decapsulation When an SRv6 packet arrives on an interface enslaved to a VRF, vrfip6rcv sets IP6SKBL3SLAVE in IP6CB, but decapandvalidate has never set IPSKBL3SLAVE in IPCB. The bi...

CVE-2026-98305

The Linux kernel contains a vulnerability in the net: dsa: mxl862xx driver where the stats poll is not correctly disabled during teardown. The mxl862xx_setup() function arms the poll before mxl862xx_setup_mdio() , but if dsa_register_switch() returns an error, the dsa_port list is freed while the...

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: restore the hardware filters on open bcmgenethfbinit runs INITLISTHEAD on priv-rxnfclist, which drops every rule off the list, and bcmgenetopen calls it on each ifup. Every rule the user configured is silently lost...

CVE-2026-98304

The Linux kernel contains a vulnerability in the bcmgenet driver where user-configured hardware filters are silently lost during an interface ifup operation. The root cause is that the bcmgenet_hfb_init() function calls INIT_LIST_HEAD() on the priv->rxnfc_list every time bcmgenet_open() is exe...

CVE-2026-98303

The Linux kernel is affected by a vulnerability in icmp_route_lookup() where RTN_UNREACHABLE input routes are not properly rejected. When a forward output route is unusable, the kernel performs a reverse path lookup via ip_route_input(). If the source address is unreachable, ip_route_input() succ...

EUVD-2026-93288

In the Linux kernel, the following vulnerability has been resolved: ipv4: icmp: reject RTNUNREACHABLE input routes in icmproutelookup When the forward output route cannot be used in icmproutelookup, it enters the "reverse path" and calls iprouteinput on fl4dec.daddr, the original packet's source...

EUVD-2026-93287

In the Linux kernel, the following vulnerability has been resolved: net: fddi: skfp: fix NULL deref when setting the MAC address while down skfpctlsetmacaddress calls ResetAdapter unconditionally, without checking netifrunning. ResetAdapter first calls cardstop, which sets smc-hw.hwstate to...

CVE-2026-98302

The Linux kernel contains a NULL pointer dereference vulnerability in the skfp (FDD-II) driver. The issue occurs because skfp_ctl_set_mac_address() calls ResetAdapter() unconditionally without verifying if the network interface is running via netif_running(). On an interface that has never been i...

CVE-2026-98301

The Linux kernel contains a vulnerability in the net: bridge: mst component where the br_mst_set_state() function calls switchdev_port_attr_set() while holding an rcu_read_lock() . This is problematic because the switchdev notifier chain can invoke blocking calls and sleep. The issue is triggered...

EUVD-2026-93286

In the Linux kernel, the following vulnerability has been resolved: net: bridge: mst: move switchdev call outside rcu This is a follow-up of one of sashiko's pre-existing bug reports. brmstsetstate calls switchdevportattrset for nonzero MSTIs while holding rcureadlock which invokes the blocking...

In the Linux kernel, the following vulnerability has been resolved: tcp: Don't call skbcloneandcharger for closed listener in tcpv6dorcv. tcpv6dorcv no longer calls skbcloneandcharger for TCPLISTEN since commit 073d89808c06 "net: fix data-races around sk-skforwardalloc". However, there is still a...

CVE-2026-98300

The Linux kernel contains a vulnerability in the tcp_v6_do_rcv() function where a race condition exists between tcp_v6_rcv() and tcp_v6_do_rcv() . A concurrent close() operation can change the state from TCP_LISTEN to TCP_CLOSE , causing skb_clone_and_charge_r() to be called locklessly. This resu...

CVE-2026-98299

The Linux kernel is vulnerable to a division by zero crash in the tcp_rcvbuf_grow() and tcp_rcv_space_adjust() functions within net/ipv4/tcp_input.c. The root cause is that if net.ipv4.tcp_rmem is configured with arbitrarily small values (e.g., 1), sk->sk_rcvbuf is initialized to 1, causing tp...
