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-2026-99088

A vulnerability exists in the Linux kernel 's OpenvSwitch component specifically within the set_ipv6_addr() function. When processing IPv6 fragments , parse_ipv6hdr() sets the protocol to NEXTHDR_FRAGMENT without calling skb_set_transport_header(). Consequently, update_ipv6_checksum() uncondition...

CVE-2026-99025

A vulnerability in the Linux kernel 's openvswitch component causes a soft lockup and system panic during a netlink flow dump . The issue occurs because ovs_flow_cmd_dump() calls ovs_flow_stats_get(), which uses spin_unlock_bh(). This repeatedly enables local softirqs, causing the dumping thread ...
