CVE-2026-64516

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vce1: Fix VCE 1 firmware size and offsets The VCPU BO contains the actual FW at an offset, but it was not calculated into the VCPU BO size. Subtract this from the FW size to make sure there is no out of bounds access...

CVE-2026-64477 x86,fs/resctrl: Prevent out-of-bounds access while offlining CPU when SNC enabled

In the Linux kernel, the following vulnerability has been resolved: x86,fs/resctrl: Prevent out-of-bounds access while offlining CPU when SNC enabled The architecture updates the cpumask in a domain's header to track which online CPUs are associated with the domain. When this mask becomes empty t...

CVE-2026-64477

CVE-2026-64477 affects Linux kernel (x86, fs/resctrl) where offlining a CPU with SNC enabled can trigger an out-of-bounds access. The root cause is that when a monitoring domain’s cpu_mask becomes empty, the NUMA node lookup uses nr_cpu_ids, leading to out-of-bounds during RMID reading. The mitig...

CVE-2026-64413 netfilter: ebtables: zero chainstack array

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: zero chainstack array sashiko reports: looking at ebtables table translation, could a sparse cpupossiblemask lead to an uninitialized pointer free? If cpupossiblemask is sparse for example, CPU 0 and CPU 2 ar...

CVE-2026-64413

CVE-2026-64413 relates to the Linux kernel netfilter/ebtables path, specifically the zero chainstack array issue. The advisory describes that if cpu_possible_mask is sparse (e.g., CPU 0 and CPU 2 possible, CPU 1 not), the allocation loop can skip an entry and, if vmalloc_node() fails later, the c...

CVE-2026-64374

CVE-2026-64374 concerns the Linux kernel’s RT scheduling path. The vulnerability stems from making RT_PUSH_IPI default off for non-PREEMPT_RT configurations, which could affect RT migration when high-priority RT tasks are scheduled across CPUs. The mechanism normally pulls RT tasks between CPUs u...
