CVE-2026-43463

Summary: Multiple sources confirm a Linux kernel vulnerability in rxrpc and afs where rxrpc_kernel_lookup_peer() could return error pointers in addition to NULL, risking instability. The fix changes rxrpc_kernel_lookup_peer() to return -ENOMEM on allocation failure (instead of NULL) and updates c...

CVE-2026-31696

A flaw was found in the Linux kernel's rxrpc component. An unprivileged user can exploit this by providing an excessively large ticket length during key preparsing. This improper validation leads to an oversized token calculation when the key is subsequently read, triggering a system warning and...

CVE-2026-31696

Summary (CVE-2026-31696) : In the Linux kernel’s rxrpc code, the non-XDR key parsing path (rxrpc_preparse()) lacked a validation check for ticket length, unlike the XDR path. This allowed an unprivileged user to supply a very large ticket length, causing the computed total token size (toksize) to...

CVE-2026-31639

A flaw was found in the rxrpc subsystem of the Linux kernel. When a client call is created, a reference to a key is obtained but not properly released when the call is destroyed. This oversight leads to a key reference count leak, which can accumulate over time. This resource exhaustion could...
