| Doc Text: |
A NULL pointer dereference flaw was found in the Xirlink camera USB driver 'xirlink-cit' in the Linux kernel. The driver mishandles invalid descriptors leading to a denial-of-service (DoS). This could allow a local attacker with user privilege to crash the system or leak kernel internal information.

Created kernel tracking bugs for this issue: Affects: fedora-all [bug 1824793] This was fixed for Fedora with the 5.5.14 stable kernel updates. Mitigation: Mitigation for this issue is to skip loading the affected module 'xirlink-cit' onto the system till we have a fix available, this can be done by a blacklist mechanism, this will ensure the driver is not loaded at the boot time. ~~~ How do I blacklist a kernel module to prevent it from loading automatically? https://access.redhat.com/solutions/41278 ~~~ This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2020:4431 https://access.redhat.com/errata/RHSA-2020:4431 This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2020:4609 https://access.redhat.com/errata/RHSA-2020:4609 This bug is now closed.
