Описание

An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/cm4000_cs.c has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling open(), aka a race condition between cmm_open() and cm4000_detach().

A possible race condition was found in drivers/char/pcmcia/cm4000_cs.c between the cmm_open() and the cm4000_detach() functions if the user physically removes the PCMCIA device in the Linux kernel. This flaw may eventually result in a use-after-free (UAF) flaw.

Меры по смягчению последствий

This flaw can be mitigated by preventing the affected CardMan Mobile 4000 kernel module from loading during the boot time. Ensure the module is added into the blacklist file.

Refer: How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278
