kernel: net/sched: act_pedit: extend the writable skb range per key

A flaw was found in the Linux kernel's traffic control packet editing pedit subsystem. In tcfpeditact, the copy-on-write COW range for skbensurewritable is computed once before iterating over edit keys, but the calculation does not account for runtime header offsets added by typed keys. This can...

CVE-2026-52997

A flaw was found in the Linux kernel's schdualpi2 qdisc queueing discipline component. When dualpi2change attempts to enforce updated limit and memory limit values, it may incorrectly try to dequeue packets from an empty C-queue while packets are present in the L-queue. This can lead to a NULL sk...

CVE-2026-52981

A flaw was found in the Linux kernel. The neighxmit function, when called with an uninitialized neighbor table such as NEIGHNDTABLE when IPv6 is disabled, can return an error without properly releasing the allocated skb socket buffer. This can lead to a memory leak, potentially impacting system...

CVE-2026-53227

A flaw was found in the Linux kernel's Open vSwitch OVS component. This issue occurs due to incorrect error handling during the allocation of a 'reply' skb socket buffer after locking the ovsmutex. If the allocation fails, an invalid pointer may be passed to kfreeskb, leading to a system crash an...

CVE-2026-53215

A flaw was found in the Linux kernel's mvpp2 network driver. This vulnerability occurs due to incorrect handling of receive RX buffers, where a buffer is returned to the hardware Buffer Manager BM pool after it has been passed to the eXpress Data Path XDP or attached to a socket buffer skb. This...

CVE-2026-52993

A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...

CVE-2026-53009

A flaw was found in the Linux kernel's ice network driver. An error in the driver's handling of network packet transmission, specifically when icetso or icetxcsum functions fail, can lead to a double-free of a network buffer skb. This occurs because a transmit buffer txbuf may still point to an...

EUVD-2026-39337

In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: fix potential unbounded skb queue virtiotransportincrxpkt checks vvs-rxbytes + len vvs-bufalloc. virtiotransportrecvenqueue skips coalescing for packets with VIRTIOVSOCKSEQEOM. If fed with packets with len == 0 and...

CVE-2026-53253

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bnep: reject short frames before parsing A BNEP peer can send a short BNEP SDU. bneprxframe reads the packet type byte immediately and, for control packets, reads the control opcode and setup UUID-size byte before...

CVE-2026-53227

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix possible kfreeskb of ERRPTR After the patch in the "Fixes" tag, the allocation of the "reply" skb can happen either before or after locking the ovsmutex. However, error cleanups still follow the classical...

CVE-2026-53215

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error path returns the current descriptor buffer to the hardware BM pool. That is only valid while the driver still owns the buffer. mvpp2rxrefill can fail after the...

CVE-2026-53151

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix the ACK parser to extract the SACK table for parsing Fix modification of the received skbuff in rxrpcinputsoftacks and a potential incorrect access of the buffer in a fragmented UDP packet the packet would probably hav...

UBUNTU-CVE-2026-53275

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: Fix use-after-free when processing MLD queries When processing an MLD query, a pointer to the multicast group address is retrieved when initially parsing the packet. This pointer is later dereferenced without being...
