kernel-rt is vulnerable to privilege escalation. A buffer overflow flaw was found in the way UTF-8 characters were converted to UTF-16 in the utf8s_to_utf16s() function of the Linux kernel’s FAT file system implementation. A local user able to mount a FAT file system with the “utf8=1” option could use this flaw to crash the system or, potentially, to escalate their privileges.
