kernel: ima: don't clear IMA_DIGSIG flag when setting or removing non-IMA xattr

In the Linux kernel, the following vulnerability has been resolved: ima: don't clear IMADIGSIG flag when setting or removing non-IMA xattr Currently when both IMA and EVM are in fix mode, the IMA signature will be reset to IMA hash if a program first stores IMA signature in security.ima and then...

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...

CVE-2026-52962

A flaw was found in the Linux kernel, specifically within the Ceph file system's extended attribute handling. A buffer leak occurs in the cephsetxattr function because a previously allocated buffer oldblob is not properly released. This can lead to resource exhaustion over time, potentially causi...

CVE-2026-53041

A flaw was found in the Linux kernel's Oracle Cluster File System version 2 OCFS2. When an OCFS2 inode has both inline and and block-based extended attributes xattrs, the listxattr function can return a size larger than the caller's buffer. This incorrect size handling can lead to a kernel bug an...

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ocfs2: fix listxattr handling when the buffer is full BUG If an OCFS2 inode has both inline and block- based xattrs, listxattr can return a size larger than the...

CVE-2026-53041

In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix listxattr handling when the buffer is full BUG If an OCFS2 inode has both inline and block-based xattrs, listxattr can return a size larger than the caller's buffer when the inline names consume that buffer exactly...

CVE-2026-52962 ceph: fix a buffer leak in __ceph_setxattr()

In the Linux kernel, the following vulnerability has been resolved: ceph: fix a buffer leak in cephsetxattr The oldblob in cephsetxattr can store ci-ixattrs.preallocblob value during the retry. However, it is never called the cephbufferput for the oldblob object. This patch fixes the issue of the...
