CVE-2026-31641

The CVE-2026-31641 entry relates to the Linux kernel rxrpc token parsing bug. A heap buffer overflow could occur when rxrpc_preparse_xdr_yfs_rxgk() reads raw key and ticket lengths from an XDR token, applies round_up(x,4), and then uses the rounded values for validation/allocation, while the unro...

CVE-2026-31635

In the Linux kernel, the following vulnerability has been resolved: rxrpc: fix oversized RESPONSE authenticator length check rxgkverifyresponse decodes authlen from the packet and is supposed to verify that it fits in the remaining bytes. The existing check is inverted, so oversized RESPONSE...

CVE-2026-31635

CVE-2026-31635 affects the Linux kernel rxrpc component. The vulnerability stems from an inverted length check in rxgk_verify_response(), where oversized RESPONSE authenticators can be accepted and later cause a contradictory length that leads to a BUG_ON(len) in skb_to_sgvec(). This can crash th...
