NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

drivers/char/pcmcia/synclink_cs.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling ioctl, aka a race condition between mgslpc_ioctl and mgslpc_detach.
