CVE-2026-98383

In the Linux kernel, the following vulnerability has been resolved: bpf: Disallow bpfskbpulldata for LWTSEG6LOCAL An LWTSEG6LOCAL program can invalidate its cached SRH with bpflwtseg6adjustsrh and then call bpfskbpulldata. The latter may reallocate skb-head, leaving the per-CPU SRH pointer...

CVE-2026-98380

In the Linux kernel, the following vulnerability has been resolved: net/sched: reject IDR error pointers when deleting actions tcfactiondelete drops the reference held by its lookup before calling tcfidrdeleteindex with the saved action index. An unlocked classifier can remove that action and...

UBUNTU-CVE-2026-98378

In the Linux kernel, the following vulnerability has been resolved: bpf: Skip unsettled links in link iterator bpflinkprime inserts a link into linkidr before anoninodegetfile succeeds and before bpflinksettle publishes the ID in link-id. bpflinkbyid treats such an ID-zero link as unsettled, but...

UBUNTU-CVE-2026-98376

In the Linux kernel, the following vulnerability has been resolved: bpf: Use arraymapmetaequal for percpu array inner map replacement percpuarraymapops.mapmetaequal points to the generic bpfmapmetaequal, which does not compare maxentries. When a percpu array serves as an inner map, replacing it...

UBUNTU-CVE-2026-98375

In the Linux kernel, the following vulnerability has been resolved: xen/netfront: drop RX packets with a short Ethernet header handleincomingqueue pulls pullto bytes into the head before calling ethtypetrans. pullto is the length of the first RX slot, capped at RXCOPYTHRESHOLD, and that length...

UBUNTU-CVE-2026-98381

In the Linux kernel, the following vulnerability has been resolved: veth: manage XDP program pointers during channel resize vethsetchannels tears down XDP resources for removed RX queues without clearing rq-xdpprog. If the program is then detached or replaced, those queues keep the old pointer...

UBUNTU-CVE-2026-98384

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix out-of-bounds read of skprotocol in bpfsockdestroy skprotocol lives in struct sock, not in struct sockcommon. A timewait or request sock handed to bpfsockdestroy by the tcp iterator is neither, so reading sk-skprotocol...

UBUNTU-CVE-2026-98382

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject dev-bound-only programs on other devices bpfoffloaddevmatch falls back to comparing offdev pointers after an exact netdev mismatch. Bound-only programs normally have NULL offdevs, so unrelated netdevs compare equal. A...

UBUNTU-CVE-2026-98379

In the Linux kernel, the following vulnerability has been resolved: netfilter: ip6trpfilter: reject routes without inet6dev ip6routelookup can return an error-free route whose rt6iidev is NULL. Lowering an external nexthop device's MTU below IPV6MINMTU tears down its inet6dev while fib6ifdown...

CVE-2026-98377

In the Linux kernel, the following vulnerability has been resolved: vlan: require the MAC header to be present in vlaninsertinnertag vlaninsertinnertag only guarantees head room via skbcowhead, never that maclen bytes of MAC header are present. Its ETHHLEN wrappers - vlaninserttag under...

CVE-2026-98272

A flaw was found in the Linux kernel's Marvell mvpp2 network driver. This vulnerability can lead to a Denial of Service DoS due to an out-of-bounds memory access. A local user with network configuration privileges can trigger this issue by altering the Maximum Transmission Unit MTU, which causes...

kernel: nvmet-rdma: handle inline data with a nonzero offset

A flaw was found in the nvmet-rdma component of the Linux kernel. This vulnerability arises from incorrect handling of inline data with a non-zero offset, which can lead to an integer underflow. An attacker could exploit this to cause the system to read beyond its allocated memory, potentially...

kernel: udp: fix potential use-after-free in tunnel segmentation

A flaw was found in the Linux kernel's UDP User Datagram Protocol tunnel segmentation. This vulnerability arises when the system attempts to process network packets, specifically in the skbudptunnelsegment function. An attacker could potentially exploit a use-after-free condition, where the syste...

CVE-2026-98201

A flaw was found in the Linux kernel's input subsystem. When handling 32-bit compatibility requests for force feedback input effects, the kernel fails to properly initialize memory buffers before copying data from user space. A local user can exploit this vulnerability to read uninitialized kerne...

CVE-2026-98262

A flaw was found in the Linux kernel's libahci driver. This issue can lead to a Denial of Service DoS when initializing storage controllers configured to use 32-bit Direct Memory Access DMA. Because the driver fails to clear the upper 32-bit memory address registers on hardware that physically...
