CVE-2026-46046

A flaw was found in the Linux kernel's ext4 filesystem. A reference count refcount leak occurs in the ext4xattrinodedecrefall function. This issue arises because the iloc.bh buffer head, acquired by ext4getinodeloc, is not properly released with brelse. This can lead to resource exhaustion or...

CVE-2026-46100

A flaw was found in the Linux kernel's AFS Andrew File System component. The mmapprepare function was incorrectly used, leading to a reference count refcount leak. This issue occurs when mmapprepare establishes a refcount, but a subsequent operation fails, causing the refcount to be leaked. This...
