Last modified

CVE-2024-26823 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3-its: Restore quirk probing for ACPI-based systems While refactoring the way the ITSs are probed, the handling of quirks applicable to ACPI-based platforms was lost. As a result, systems such as HIP07 lose their GICv4 functionnality, and some other may even fail to boot, unless they are configured to boot with DT. Move the enabling of quirks into its_probe_one(), making it common to all firmware implementations.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
