CVE-2026-46331

CVE-2026-46331 affects the Linux kernel’s net/sched packet editing path, specifically the per-key handling in act_pedit where the writable Copy-on-Write (COW) region was calculated before the actual write offset was known. The runtime header offset from typed keys could leave portions of memory u...

kernel: net: skbuff: propagate shared-frag marker through frag-transfer helpers

A flaw was found in the Linux kernel's networking skbuff component. When skbtrycoalesce attaches paged fragments, it can lose the SKBFLSHAREDFRAG marker. This can lead to the Encapsulating Security Payload ESP input decrypting data in place over page-cache backed fragments, potentially resulting ...

kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...

FreeBSD Security Advisory - FreeBSD-SA-26:26.ktls

FreeBSD Security Advisory - The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile2, which can reference file-backed memory directly through...
