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...

rsync: Rsync: Use-after-free vulnerability in extended attribute handling

A flaw was found in rsync. When rsync is configured to handle extended attributes using the -X or --xattrs option, a remote attacker can exploit a use-after-free vulnerability. This occurs because the receivexattr function incorrectly processes an untrusted length value during a sorting operation...
