CVE-2026-93801

A flaw was found in the Linux kernel's SMB (Server Message Block) client. Certain file information structures allocated on the stack are not zero-initialized, leaving them containing random data when specific fields are not explicitly set. A local user performing file operations on a mounted SMB share could cause the kernel to process this uninitialized memory. This vulnerability can lead to a Denial of Service (DoS) via a system crash or result in unexpected kernel behavior.
