CVE-2026-23377

CVE-2026-23377 affects the Linux kernel in the ice network driver under XDP. The root cause is an incorrect use of frag_size in XDP RxQ info, which should reflect the whole buffer size but was treated as a DMA write length, causing negative tailroom and potential kernel panic when crafting packet...

CVE-2026-23343 xdp: produce a warning when calculated tailroom is negative

In the Linux kernel, the following vulnerability has been resolved: xdp: produce a warning when calculated tailroom is negative Many ethernet drivers report xdp Rx queue frag size as being the same as DMA write size. However, the only user of this field, namely bpfxdpfragsincreasetail, clearly...

In the Linux kernel, the following vulnerability has been resolved: net: fix udp gso skbsegment after pull from fraglist Commit a1e40ac5b5e9 net: gso: fix udp gso fraglist segmentation after pull from fraglist detected invalid geometry in fraglist skbs and redirects them from skbsegmentlist to mo...

The vulnerabilities of the functions mptcp_sendmsg_frag() and mptcp_subflow_get_send() in the module net/mptcp/protocol.c, which are part of the MPTCP protocol implementation in Linux kernel, allow attackers to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerabilities of the functions mptcpsendmsgfrag and mptcpsubflowgetsend in the net/mptcp/protocol.c module of the Linux operating system’s MPTCP implementation are related to insufficient resource locking. Exploiting these vulnerabilities could allow an attacker to compromise the...
