CVE-2026-68436

The CVE-2026-68436 issue affects the Linux kernel DRM for AMD display: the in-kernel struct dc can grow beyond the 4 MiB contiguous allocation limit, causing dc_create() to fail when allocated with kzalloc(). The fix replaces kzalloc() with kvzalloc() (and kvfree()) so allocation can fall back to...

CVE-2026-63809

A flaw was found in the Linux kernel. An issue in the BPF Berkeley Packet Filter subsystem's sysctl handling can lead to memory corruption. Specifically, when a temporary buffer is allocated using kvzalloc but incorrectly freed with kfree, it can corrupt memory. A local attacker could exploit thi...

CVE-2026-63809

CVE-2026-63809 affects the Linux kernel memory-management path used by BPF when handling proc sysctl writes. The vulnerability stems from proc_sys_call_handler() allocating a temporary sysctl buffer with kvzalloc() and passing it to __cgroup_bpf_run_filter_sysctl(); since kvzalloc() may fall back...

CVE-2026-53285

A flaw was found in the Linux kernel's drm/amd/display component. When the dcn32enablephantomplane function attempts to allocate memory using kvzalloc within a floating-point unit FPU enabled region where software interrupts softirqs are disabled, it can trigger an error. This can lead to a kerne...
