CVE-2026-31649

The CVE-2026-31649 issue affects the Linux kernel’s stmmac driver, where jumbo_frm() can underflow when processing fragmented packets. If nopaged_len is small but skb->len is large, len = nopaged_len - buf_len (with buf_len clamped to min(nopaged_len, bmax)) can still yield a large unsigned va...

CVE-2026-31551

The CVE-2026-31551 entry relates to the Linux kernel mac80211 wifi subsystem. A race in aql_enable_write() during concurrent debugfs writes can cause a static_branch_dec() underflow because the code checks static_key_false(&aql_disable.key) and then later increments/decrements the static branch, ...
