CVE-2026-74560

In the Linux kernel, the following vulnerability has been resolved: xsk: fix buffer leak in xskdropskb for AFXDP multi-buffer Tx This patch is inspired by the check1 from sashiko. It says when overflow happens, the address of cq to be published is invalid. Actually the severer thing is the whole...

CVE-2026-74559

CVE-2026-74559 affects the Linux kernel XDP/AF_XDP path. The issue arises in the xsk_build_skb() flow where, on overflow of descriptors (or invalid descriptors in fragmented packets), the generic transmit path multi-buffer handling could mishandle descriptors. The fix introduces xdp_sock::drain_c...

CVE-2026-74558

CVE-2026-74558 describes a Linux kernel vulnerability in the xsk ZC (zero-copy) batch path. The issue arises when the zero-copy Tx batch parser encounters an invalid descriptor or when a packet exceeds xdp_zc_max_segs. In these cases, descriptors can be misinterpreted, potentially advancing the T...

CVE-2026-74557

CVE-2026-74557 (Linux kernel) affects the SCSI/libiscsi path. The bug occurs in iscsi_scsi_cmd_rsp(): it copies sense data from a target-provided segment that starts with a 2-byte sense length, but the bounds check only verified datalen against senselen. As a result, when datalen equals senselen ...
