CVE-2026-92515 bpf: Preserve unique-field state across nested structs

In the Linux kernel, the following vulnerability has been resolved: bpf: Preserve unique-field state across nested structs btffindstructfield initializes a fresh seen mask for every recursive descent. Unique special fields in different levels of the same aggregate therefore do not see one another...

CVE-2026-93148: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject MEMALLOC BTF accesses past object bounds BTF struct walks relax the struct-size check for accesses through a trailing flexible array. That is valid for ordinary BTF type walking, but PTRTOBTFID | MEMALLOC values point...
