CLSA-2026-1780054763 Fix CVE(s): CVE-2026-41035

SECURITY UPDATE: use-after-free in receivexattr - debian/patches/CVE-2026-41035.patch: replace stale local 'count' with tempxattr.count in the qsort call inside receivexattr, so the sort uses the live size of the rebuilt xattr items list; victim must run rsync with -X / --xattrs - CVE-2026-41035...

kernel: xfs: fix freemap adjustments when adding xattrs to leaf blocks

A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes xattrs, which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion...

FreeBSD : FreeBSD -- Heap overflow in FUSE_LISTXATTR (3cc34467-54b6-11f1-8d7a-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 3cc34467-54b6-11f1-8d7a-bc241121aa0a advisory. When a fusefs file system implements extended attributes, the kernel may send a FUSELISTXATTR message t...

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...

OESA-2026-2150 rsync security update

Rsync is an open source utility that provides fast incremental file transfer. It uses the "rsync algorithm" which provides a very fast method for bringing remote files into sync. It does this by sending just the differences in the files across the link, without requiring that both sets of files a...

CVE-2026-35354

The CVE concerns the mv utility from uutils coreutils, where a TOCTOU race occurs during cross-device moves. The xattr preservation logic uses several path-based system calls that re-resolve inodes between operations, allowing a local attacker with directory write access to swap files during the ...

PT-2026-34490

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the mv utility of uutils coreutils during cross-device moves. The extended attribute xattr preservation logic uses multiple path-based system calls that perform fresh path-to-inode lookups for each operation. A local attacker with writ...

Updated rsync packages fix security vulnerability

In rsync 3.0.1 through 3.4.1, receivexattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X aka --xattrs. On Linux, many but not all common configurations are vulnerable. Non-Linux platforms are more widely vulnerable...
