CVE-2026-53085

The CVE-2026-53085 issue affects the Linux kernel BPF subsystem where the open-coded task_vma iterator reads task->mm locklessly and uses mmap_read_trylock() without taking an mm reference, risking use-after-free if the task exits concurrently. The patch reads task->mm with a trylock on all...

EUVD-2026-38953

In the Linux kernel, the following vulnerability has been resolved: bpf: fix mm lifecycle in open-coded taskvma iterator The open-coded taskvma iterator reads task-mm locklessly and acquires mmapreadtrylock but never calls mmget. If the task exits concurrently, the mmstruct can be freed as it is...

CVE-2026-53084 bpf: return VMA snapshot from task_vma iterator

In the Linux kernel, the following vulnerability has been resolved: bpf: return VMA snapshot from taskvma iterator Holding the per-VMA lock across the BPF program body creates a lock ordering problem when helpers acquire locks that depend on mmaplock: vmlock - irwsem - mmaplock - vmlock Snapshot...

CVE-2026-53033 bpf, sockmap: Take state lock for af_unix iter

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Take state lock for afunix iter When a BPF iterator program updates a sockmap, there is a race condition in unixstreambpfupdateproto where the peer pointer can become stale1 during a state transition TCPESTABLISHED ...

CVE-2026-53033 bpf, sockmap: Take state lock for af_unix iter

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 nvmet-tcp: propagate nvmet_tcp_build_pdu_iovec() errors to its callers

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: propagate nvmettcpbuildpduiovec errors to its callers Currently, when nvmettcpbuildpduiovec detects an out-of-bounds PDU length or offset, it triggers nvmettcpfatalerrorcmd-queue and returns early. However, because the...

However, because the...

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...
