CVE-2026-53125

CVE-2026-53125 affects the Linux kernel. When user-space writes “clear” to /sys/block/md*/md/array_state, md_attr_store() drops the mddev reference before sysfs_unbreak_active_protection(), which can cause the last kobject reference to be dropped while the mddev is still eligible for deletion. Th...

In the Linux kernel, the following vulnerability has been resolved: amd-pstate: Fix memory leak in amdpstateeppcpuinit On failure to set the epp, the function amdpstateeppcpuinit returns with an error code without freeing the cpudata object that was allocated at the beginning of the function...

CVE-2026-53066

CVE-2026-53066 affects the Linux kernel DRM sun4i backend. The flaw is that drm_atomic_get_plane_state() may return an error pointer which is not checked in sun4i_backend_atomic_check(), allowing a dereference of ERR_PTR() and potential kernel instability. Public details cite a fix in the kernel ...

CVE-2026-53033

CVE-2026-53033 affects the Linux kernel’s BPF sockmap path, causing a race in unix_stream_bpf_update_proto() that can yield a Use-After-Free when a BPF iterator updates a sockmap during a TCP state transition. The issue is resolved by taking the state lock for AF_UNIX iterations to keep the unix ...

CVE-2026-52989

CVE-2026-52989 affects the Linux kernel nvmet-tcp component. The root cause is that nvmet_tcp_build_pdu_iovec() detects out-of-bounds PDU length/offset but does not propagate the error to callers; it returns void and triggers nvmet_tcp_fatal_error(cmd->queue) without alerting the caller, leavi...
