Upgrade Rocky-Linux:8 kernel to version 0:4.18.0-553.16.1.el8_10 or higher.
This issue was patched in RLSA-2024:5101.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by Rocky-Linux.
See How to fix? for Rocky-Linux:8 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3-its: Prevent double free on error
The error handling path in its_vpe_irq_domain_alloc() causes a double free when its_vpe_init() fails after successfully allocating at least one interrupt. This happens because its_vpe_irq_domain_free() frees the interrupts along with the area bitmap and the vprop_page and its_vpe_irq_domain_alloc() subsequently frees the area bitmap and the vprop_page again.
Fix this by unconditionally invoking its_vpe_irq_domain_free() which handles all cases correctly and by removing the bitmap/vprop_page freeing from its_vpe_irq_domain_alloc().
