CVE-2024-26872 Open this link in a new tabHow to fix?
Upgrade RHEL:8 kernel-debug-core to version 0:4.18.0-553.5.1.el8_10 or higher.
This issue was patched in RHSA-2024:3618.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-debug-core package and not the kernel-debug-core package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: Do not register event handler until srpt device is fully setup
Upon rare occasions, KASAN reports a use-after-free Write in srpt_refresh_port().
This seems to be because an event handler is registered before the srpt device is fully setup and a race condition upon error may leave a partially setup event handler in place.
Instead, only register the event handler after srpt device initialization is complete.
