CVE-2026-98289

The Linux kernel contains a vulnerability in the af_unix component related to how Tarjan's algorithm handles SCC (Strongly Connected Component) indices. Specifically, the unix_vertex_dead() function assumes all vertices in an SCC share the same lowpoint (scc_index), but this assumption fails if a...

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: fix TSO header length truncation stmmactsoxmit stores the protocol header length returned by stmmactsoheadersize in a u8. stmmactsovalidpacket admits headers up to 1023 bytes, so a header longer than 255 bytes wraps...

CVE-2026-98288

The Linux kernel contains a vulnerability in the stmmac driver where stmmac_tso_xmit() incorrectly stores the protocol header length in a u8 variable. Because stmmac_tso_valid_packet() allows headers up to 1023 bytes, any header exceeding 255 bytes—such as a TCP over IPv6 socket with specific des...

In the Linux kernel, the following vulnerability has been resolved: pppoatm: ensure a writable skb header and linear data In pppoatmsend, LLC encapsulation checks whether there is sufficient headroom for the 4-byte LLC header, but does not ensure that the skb header is writable. Normal transmit...

CVE-2026-98287

The Linux kernel contains a vulnerability in the pppoatm component where the pppoatm_send() function fails to ensure the skb header is writable when performing LLC encapsulation. While standard packets use skb_cow_head(), packets arriving via PPP channel bridging (PPPIOCBRIDGECHAN) bypass this ch...
