CVE-2026-43378

A flaw was found in the Linux kernel. Specifically, within the Server Message Block SMB server component, a use-after-free vulnerability exists in the smb2open function. This issue arises when an opinfo pointer is accessed after its memory has been deallocated, creating a window for potential...

CVE-2026-43362

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability allows a remote attacker to cause data corruption. When an SMB client attempts to write data over an unstable connection, the in-place encryption process can lead to already encrypted data being re-sent...
