K000162731: Linux kernel vulnerability CVE-2026-63793

Security Advisory Description In the Linux kernel, the following vulnerability has been resolved: ntfs: serialize volume label accesses Protect vol-volumelabel with a mutex and snaphost the label before copytouser. This prevent a use-after-free when FSIOCSETFSLABEL replaces the vol-volumelabel an...

CVE-2026-63793

A flaw was found in the Linux kernel's NTFS file system driver. This vulnerability, a use-after-free, arises from insufficient protection during concurrent operations on the volume label. A local attacker could exploit this by simultaneously setting and getting the file system label, which may le...

CVE-2026-63793

CVE-2026-63793 affects the Linux kernel’s NTFS handling. The issue arises from unsafe concurrent access to vol->volume_label during FS_IOC_SETFSLABEL and FS_IOC_GETTSLABEL, which could lead to a use-after-free. The patch inserts a mutex to guard the volume_label and snapshots the label before ...
