CVE-2026-98613

The Linux kernel contains a vulnerability where program-allocated objects can own other local objects via referenced kptrs . The bpf_obj_free_fields() function follows these pointers synchronously through __bpf_obj_drop_impl() before RCU-based freeing. This allows self-referential local kptr type...

CVE-2026-98613 bpf: Bound ownership depth through local kptrs and graph roots

In the Linux kernel, the following vulnerability has been resolved: bpf: Bound ownership depth through local kptrs and graph roots Program-allocated objects can own other local objects through referenced kptrs. bpfobjfreefields follows those pointers through bpfobjdropimpl synchronously, before t...

EUVD-2026-103573

In the Linux kernel, the following vulnerability has been resolved: gpio: cdev: fix kernel stack leak to user-space in error path If we fail to acquire the GPIO chip guard in gpiodesctolineinfo, we return immediately before zeroing the info struct we'll end up passing to the user-space later in...

CVE-2026-98528

The Linux kernel contains a vulnerability in the gpio cdev component where a failure to acquire the GPIO chip guard in gpio_desc_to_lineinfo() causes the function to return prematurely. This results in a kernel stack leak to user-space because the information structure is not zeroed before being ...

CVE-2026-98466 KVM: arm64: Transfer the hyp stack pages out of the host stage-2

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Transfer the hyp stack pages out of the host stage-2 fixhostownership walks only the linear-map alias of each memblock region, and the per-CPU hyp stack, mapped in the private VA range for its guard page, has none. Wa...

CVE-2026-98466

A flaw exists in the Linux kernel's KVM subsystem on ARM64 platforms. During protected virtualization mode initialization, the hypervisor fails to revoke host stage-2 access permissions for per-CPU hypervisor stack memory pages because the fix_host_ownership() function fails to walk the private V...
