CVE-2022-45919

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.10

Description The issue is related to a use-after-free condition in the Linux kernel's DVB driver, specifically in the drivers/media/dvb-core/dvb ca en50221.c module. This occurs when a device is closed after being disconnected, due to the lack of a wait event. Exploitation of this issue could allow an attacker to cause a denial of service or elevate their privileges.

Recommendations For Linux kernel versions prior to 6.0.10, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the vulnerable module drivers/media/dvb-core/dvb ca en50221.c to minimize the risk of exploitation.
