CVE-2022-44033

Опубликовано: 18 сент. 2022
Источник: redhat
CVSS3: 6.4

Описание

An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/cm4040_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 cm4040_open() and reader_detach().

A use-after-free flaw was found in the Linux Kernel. This issue occurs due to a race between cm4040_open() and reader_detach() in drivers/char/pcmcia/cm4040_cs.c when a physically proximate attacker removes a PCMCIA device while calling open().

Меры по смягчению последствий

This flaw can be mitigated by preventing the affected CardMan 4040 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
