CVE-2022-49855

A flaw was found in the Linux kernel's iosm module. A memory leak can occur due to a missing memory release of memory used to read power state configuration from BIOS, potentially impacting system performance and resulting in a denial of service.

The iosm module is not built in the Linux kernel as shipped in Red Hat Enterprise Linux 6, 7 and 8, so these Red Hat Enterprise Linux versions are not affected by this vulnerability.

The iosm module as shipped in Red Hat Enterprise Linux 10 is not affected by this vulnerability because the vulnerable code is not present.

This issue has been fixed in Red Hat Enterprise Linux 9.3 via RHSA-2023:6583 [1].
