SUSE CVE-2026-31705

In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix out-of-bounds write in smb2getea EA alignment smb2getea applies 4-byte alignment padding via memset after writing each EA entry. The bounds check on buffreelen is performed before the value memcpy, but the alignment...

CVE-2026-31705

A flaw was found in the ksmbd component of the Linux kernel. This out-of-bounds write vulnerability occurs when processing Server Message Block SMB extended attribute EA information. Specifically, the smb2getea function performs an unconditional memory write for alignment padding without checking...

CVE-2026-43053

CVE-2026-43053 affects the Linux kernel XFS filesystem. The flaw arises during inode inactivation with node-format extended attributes: xfs_attr3_node_inactive() invalidates child blocks but does not remove their references from the parent, creating a window where the parent can point to cancelle...
