Linux Kernel Vulnerability in Crypto Functionality Affecting Data Integrity

CVE-2026-63805

What is CVE-2026-63805?

A vulnerability in the Linux kernel's crypto functionality may lead to data integrity issues, specifically when handling context exits incorrectly. The issue stems from the nx_crypto_ctx_shash_exit function calling nx_crypto_ctx_exit with a mismatched argument type, potentially causing kernel access violations and crashes. This situation can result in unauthorized access to sensitive data or a denial of service if exploited. Developers should apply the patch addressing this vulnerability to maintain the security and stability of their systems.
