CVE-2026-46085 Details
Description
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix rxkad crypto unalignment handling Fix handling of a packet with a misaligned crypto length. Also handle non-ENOMEM errors from decryption by aborting. Further, remove the WARN_ON_ONCE() so that it can't be remotely triggered (a trace line can still be emitted).
A vulnerability related to misaligned crypto lengths in RXRPC packets has been addressed in the Linux kernel. The issue arose because the decryption process could encounter non-ENOMEM errors, leading to improper handling of such packets. The vulnerability was further compounded by a WARN_ON_ONCE() statement that could be remotely triggered. This fix ensures that crypto lengths are properly aligned and that the decryption process correctly manages errors, enhancing the overall stability and security of the RXRPC implementation.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
