CVE-2026-53085
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
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-2026-53083
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix RCU stall in bpffdarraymapclear Add a missing condresched in bpffdarraymapclear loop. For PROGARRAY maps with many entries this loop calls progarraymappokerun per entry which can be expensive, and without yielding this c...

In the Linux kernel, the following vulnerability has been resolved: bpf: Enforce regsafe base id consistency for BPFADDCONST scalars When regsafe compares two scalar registers that both carry BPFADDCONST, checkscalarids maps their full compound id aka base | BPFADDCONST flag as one idmap entry...
CVE-2026-53081
The CVE-2026-53081 issue affects the Linux kernel BPF verifier: when two scalar registers carry BPF_ADD_CONST, id mapping could become inconsistent because the compound id (base | ADD_CONST) was mapped without validating the underlying base IDs. This could allow two verifier states where one deri...
