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...

CVE-2026-23013

In the Linux kernel, the following vulnerability has been resolved: net: octeonepvf: fix freeirq devid mismatch in IRQ rollback octepvfrequestirqs requests MSI-X queue IRQs with devid set to ioqvector. If requestirq fails part-way, the rollback loop calls freeirq with devid set to 'oct', which do...

SUSE CVE-2025-71158

In the Linux kernel, the following vulnerability has been resolved: gpio: mpsse: ensure worker is torn down When an IRQ worker is running, unplugging the device would cause a crash. The sealevel hardware this driver was written for was not hotpluggable, so I never realized it. This change uses a...

CVE-2026-22987

CVE-2026-22987 concerns the Linux kernel net/sched subsystem. The issue arises when tcf_idrinfo_destroy() can pass an ERR_PTR(-EBUSY) as a tc_action pointer during netns teardown, leading to a dereference of an error pointer in tc_act_in_hw(). The fix adds a guard to skip ERR_PTR entries while it...
