pipe-primitive

pipe-primitive An exploit primitive in linux kernel inspired by DirtyPipe CVE-2022-0847. A while ago, like many security veterans, I studied and reproduced the DirtyPipe CVE-2022-0847 vulnerability, and deeply felt how useful this bug is. It starts from an uninitialized memory issue and ends with...

CVE-2026-98643

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. This flaw can lead to information disclosure when a BPF socket operations program reads the round-trip time rttmin field during TCP connection handling. Because the kernel fails to verify the socket type before casting i...

CVE-2026-98645

A flaw was found in the Linux kernel's Winwing Human Interface Device HID driver.
