Specifically, the loop utilize...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/msm: Do not free the IRQ if it was not requested. Since the msmdrmuninit function is called from the msmdrminit error path, additional care is necessary to avoid calling freeirq for the IRQ that was not requested. This issue...

PT-2026-64550

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A use-after-free issue exists in the USB Type-C UCSI CCG driver. The threaded IRQ handler ccg irq handler invokes ucsi notify common, which may trigger ucsi connector change and schedule...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: Firewire: ohci: prevents leakage of leftover IRQs when unbinding The commit 5a95f1ded28691e6 “Firewire: ohci: uses a devres for the requested IRQ” also removed the call to freeirq in pciremove. This resulted in a leftover IRQ...

CVE-2026-23013

CVE-2026-23013 pertains to the Linux kernel: in the octeon_ep_vf IRQ handling, the rollback path frees IRQs with a mismatched dev_id, using the literal 'oct' instead of the original ioq_vector. This can leave irqaction registrations alive, causing a use-after-free or crash when the interrupt fire...
