CVE-2026-98831

The Linux kernel contains a memory leak vulnerability in the of/overlay component. During the execution of init_overlay_changeset(), if find_target() or the __symbols__ lookup fails mid-process, the target and overlay references for fragments initialized up to that point are not released. This oc...

CVE-2026-98830

The Linux kernel contains a vulnerability in the wifi: wfx component. The function wfx_hif_read_mib() fails to validate that the reply->length from a firmware response does not exceed the val_len of the caller-provided buffer. This lack of bounds checking allows a firmware response with an ove...

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: drop oversized fragments to avoid extralen overflow In ieee80211rxhdefragment, fragment payloads are accumulated into entry-extralen as subsequent fragments arrive: entry-extralen += rx-skb-len; When the final...

CVE-2026-98829

The Linux kernel contains a vulnerability in the mac80211 component where oversized fragments can cause an extra_len overflow . The root cause is that entry->extra_len was narrowed from unsigned int to u16 to reduce memory footprint. When a sequence of large fragments exceeds 65535 bytes, the ...
