Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: 9p: add missing locking around taking
 dentry fid list Fix a use-after-free on dentry's d_fsdata fid list when a thread looks up a fid through
 dentry while another thread unlinks it: UAF thread: refcount_t: addition on 0; use-after-free. p9_fid_get
 linux/./include/net/9p/client.h:262 v9fs_fid_find+0x236/0x280 linux/fs/9p/fid.c:129
 v9fs_fid_lookup_with_uid linux/fs/9p/fid.c:181 v9fs_fid_lookup+0xbf/0xc20 linux/fs/9p/fid.c:314
 v9fs_vfs_getattr_dotl+0xf9/0x360 linux/fs/9p/vfs_inode_dotl.c:400 vfs_statx+0xdd/0x4d0 linux/fs/stat.c:248
 Freed by: p9_fid_destroy (inlined) p9_client_clunk+0xb0/0xe0 linux/net/9p/client.c:1456 p9_fid_put
 linux/./include/net/9p/client.h:278 v9fs_dentry_release+0xb5/0x140 linux/fs/9p/vfs_dentry.c:55
 v9fs_remove+0x38f/0x620 linux/fs/9p/vfs_inode.c:518 vfs_unlink+0x29a/0x810 linux/fs/namei.c:4335 The
 problem is that d_fsdata was not accessed under d_lock, because d_release() normally is only called once
 the dentry is otherwise no longer accessible but since we also call it explicitly in v9fs_remove that lock
 is required: move the hlist out of the dentry under lock then unref its fids once they are no longer
 accessible. (CVE-2024-39463)

Solution

Update the sys-kernel/lakitu-kernel-6_1 library and its related packages to version 18514.0.0 or later.
