CVE-2026-89649

CVE-2026-89649 affects the Linux kernel's CephFS subsystem. The function __build_xattrs() decodes xattr blobs supplied by the Ceph metadata server (MDS) but fails to verify that the final attribute's value length does not exceed the remaining bytes in the blob — it advances the pointer with a bar...

EUVD-2026-76561

In the Linux kernel, the following vulnerability has been resolved: ceph: bound xattr value length in buildxattrs buildxattrs decodes the MDS-supplied xattr blob one attribute at a time. For each attribute it reads a 32-bit name length, advances past the name bytes, reads a 32-bit value length,...

CVE-2022-49890

CVE-2022-49890 covers a Linux kernel memleak in cap_inode_getsecurity() when using vfs_getxattr_alloc() to allocate tmpbuf. If tmpbuf allocation succeeds but handler->get() fails, memory leak could occur in the sequence (krealloc of xattr_value, then assignment back to *xattr_value). The mitig...

The vulnerability of the __jfs_getxattr() and jfs_listxattr() functions in the Linux file system jfs allows a attacker to cause a service failure.

The vulnerability of the jfsgetxattr and jfslistxattr functions in the fs/jfs/xattr.c file of the JFS file system in the Linux operating system is related to reading memory beyond the allocated buffer. Exploiting this vulnerability could allow an attacker to cause a service failure...

kernel: capabilities: fix potential memleak on error path from vfs_getxattr_alloc()

A flaw was found in the capabilities subsystem in the Linux kernel. When memory is allocated for a temporary buffer and a subsequent function call fails, the allocated memory is not released, resulting in a memory leak. This issue could impact system performance and result in a denial of service...
