In drivers/media/dvb-core/dmxdev.c in the Linux kernel through 5.19.10, there is a use-after-free caused by refcount races, affecting dvb_demux_open and dvb_dmxdev_release. En el archivo drivers/media/dvb-core/dmxdev.c en el kernel de Linux versiones hasta 5.19.10, se presenta un uso de memoria previamente liberada causado por refcount races, que afecta a dvb_demux_open y dvb_dmxdev_release A use-after-free flaw was found in the Linux kernel’s dvb-core subsystem (DVB API used by Digital TV devices) in how a user physically removed a USB device (such as a DVB demultiplexer device) while running malicious code. This flaw allows a local user to crash or potentially escalate their privileges on the system. • https://github.com/Tobey123/CVE-2022-41218 http://www.openwall.com/lists/oss-security/2022/09/23/4 http://www.openwall.com/lists/oss-security/2022/09/24/1 http://www.openwall.com/lists/oss-security/2022/09/24/2 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fd3d91ab1c6ab0628fe642dd570b56302c30a792 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/log/drivers/media/dvb-core/dmxdev.c https://lists.debian.org/debian-lts-ann • CWE-416: Use After Free •
