CVE-2023-23039

Published: 22 February 2023

An issue was discovered in the Linux kernel through 6.2.0-rc2. drivers/tty/vcc.c has a race condition and resultant use-after-free if a physically proximate attacker removes a VCC device while calling open(), aka a race condition between vcc_open() and vcc_remove().
