CVE-2026-45927

In the Linux kernel, the following vulnerability has been resolved: bpf: Require frozen map for calculating map hash Currently, bpfmapgetinfobyfd calculates and caches the hash of the map regardless of the map's frozen state. This leads to a TOCTOU bug where userspace can call BPFOBJGETINFOBYFD t...

CVE-2026-45927

The CVE-2026-45927 issue affects the Linux kernel BPF subsystem. bpf_map_get_info_by_fd caches the hash of a map regardless of its frozen state, enabling a TOCTOU where a trusted loader could compare an older hash after a map is modified but before freezing. The fix returns -EPERM when the hash i...

CVE-2026-45908

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Fix memory leak in amdxdnaubufmap The amdxdnaubufmap function allocates memory for sg and internal sg table structures, but it fails to free them if subsequent operations sgalloctablefrompages or dmamapsgtable fail...

CVE-2026-45908

The CVE-2026-45908 issue affects the Linux kernel’s accel/amdxdna component, specifically amdxdna_ubuf_map. The function allocates memory for sg and internal sg table structures but does not free them if subsequent operations (sg_alloc_table_from_pages or dma_map_sgtable) fail, resulting in a mem...

CVE-2026-45886 bpf: Fix bpf_xdp_store_bytes proto for read-only arg

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix bpfxdpstorebytes proto for read-only arg While making some maps in Cilium read-only from the BPF side, we noticed that the bpfxdpstorebytes proto is incorrect. In particular, the verifier was throwing the following error...

CVE-2026-45886

CVE-2026-45886: In the Linux kernel, a patch fixes the bpf_xdp_store_bytes prototype for read-only arguments. The issue caused the verifier to treat the third argument as a BPF_WRITE target when NATed map memory was read-only, resulting in a forbidden write to a read-only map. The patch adjusts t...
