SUSE CVE-2026-31643

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix key parsing memleak In rxrpcpreparsexdryfsrxgk, the memory attached to token-rxgk can be leaked in a few error paths after it's allocated. Fix this by freeing it in the "rejecttoken:" case...

CVE-2026-31631

A flaw was found in the Linux kernel, specifically within its rxrpc communication protocol. This vulnerability is a buffer overread, meaning the system attempts to read data beyond the allocated memory buffer in the rxgkdoverifyauthenticator function. This could potentially allow an attacker to...

CVE-2026-31633

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix integer overflow in rxgkverifyresponse In rxgkverifyresponse, there's a potential integer overflow due to rounding up tokenlen before checking it, thereby allowing the length check to be bypassed. Fix this by checking...

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...
