CVE-2024-26689

CVE-2024-26689 affects the Linux kernel via the Ceph subsystem: in fs/ceph/caps.c, encode_cap_msg() previously could perform a use-after-free due to a race between refcount increment and free in arg->xattr_buf handling. The race around ceph_buffer_get/ceph_buffer_put(ci->i_xattrs.blob) allo...

CVE-2024-26689

In the Linux kernel, the following vulnerability has been resolved: ceph: prevent use-after-free in encodecapmsg In fs/ceph/caps.c, in encodecapmsg, "use after free" error was caught by KASAN at this line - 'cephbuffergetarg-xattrbuf;'. This implies before the refcount could be increment here, it...
