CVE ID : CVE-2026-23201<\/p>\n

Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
ceph: fix oops due to invalid pointer for kfree() in parse_longname()<\/p>\n
This fixes a kernel oops when reading ceph snapshot directories (.snap),
\nfor example by simply running `ls \/mnt\/my_ceph\/.snap`.<\/p>\n
The variable str is guarded by __free(kfree), but advanced by one for
\nskipping the initial ‘_’ in snapshot names. Thus, kfree() is called
\nwith an invalid pointer. This patch removes the need for advancing the
\npointer so kfree() is called with correct memory pointer.<\/p>\n
Steps to reproduce:<\/p>\n
1. Create snapshots on a cephfs volume (I’ve 63 snaps in my testcase)<\/p>\n
2. Add cephfs mount to fstab
\n$ echo “samba-fileserver@.files=\/volumes\/datapool\/stuff\/3461082b-ecc9-4e82-8549-3fd2590d3fb6 \/mnt\/test\/stuff ceph acl,noatime,_netdev 0 0” >> \/etc\/fstab<\/p>\n
3. Reboot the system
\n$ systemctl reboot<\/p>\n
4. Check if it’s really mounted
\n$ mount | grep stuff<\/p>\n
5. List snapshots (expected 63 snapshots on my system)
\n$ ls \/mnt\/test\/stuff\/.snap<\/p>\n
Now ls hangs forever and the kernel log shows the oops.<\/p>\n
Severity: 0.0 | NA<\/p>\n
