Description
A flaw was found in the Linux kernel. The statmount_string() function, when processing STATMOUNT_MNT_UIDMAP or STATMOUNT_MNT_GIDMAP flags, fails to initialize an offset pointer (offp). This oversight can lead to an uninitialized dereference when the pointer is later accessed. A local attacker could exploit this vulnerability to cause a denial of service (system crash).
