CVE-2026-92515

CVE-2026-92515 affects the Linux kernel BPF subsystem, specifically the BTF (BPF Type Format) field-traversal logic. The root cause is that btf_find_struct_field() re-initializes its seen mask on every recursive descent, so unique special fields at different nesting levels of the same aggregate a...

EUVD-2026-82136

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-2026-92514

CVE-2026-92514 is a use-after-free vulnerability in the Linux kernel's RDMA/erdma driver. During CEQ (Completion Event Queue) teardown, erdma_ceqs_uninit() calls free_irq(), which waits for an in-flight hard-IRQ handler but does not drain a tasklet that the handler already scheduled. That tasklet...
