CVE-2026-43244

A flaw was found in the Linux kernel's Kernel Connection Multiplexer KCM module. A local user could trigger an issue where, during partial sendmsg operations, an empty network buffer skb is incorrectly left in the fraglist. A subsequent zero-length write operation can then cause a kernel warning,...

CVE-2026-43093

A flaw was found in the Linux kernel's xsk AFXDP subsystem due to insufficient validation of the User Memory UMEM headroom. This vulnerability could lead to memory corruption, specifically the skbsharedinfo data structure, if multi-buffer is enabled. Such corruption could result in system...
