CVE-2026-52962

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...

CVE-2026-52962

CVE-2026-52962 relates to the Linux kernel patch addressing a buffer leak in Ceph’s __ceph_setxattr() path. The issue arises because old_blob (ci->i_xattrs.prealloc_blob) could be retained during a retry and was not released via ceph_buffer_put(), leading to a leak. The patch fixes the leak by...
