CVE-2022-48804 Open this link in a new tabHow to fix?
There is no fixed version for RHEL:9 kernel-zfcpdump-modules-internal.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-zfcpdump-modules-internal package and not the kernel-zfcpdump-modules-internal package as distributed by RHEL.
See How to fix? for RHEL:9 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
vt_ioctl: fix array_index_nospec in vt_setactivate
array_index_nospec ensures that an out-of-bounds value is set to zero on the transient path. Decreasing the value by one afterwards causes a transient integer underflow. vsa.console should be decreased first and then sanitized with array_index_nospec.
