CVE-2026-90303

CVE-2026-90303 affects the Linux kernel on ARM architecture. When CONFIG_DEBUG_USER=y and the kernel command-line option user_debug=31 are active, a user fault can trigger show_pte() without holding any lock. If another thread in the same process concurrently calls munmap() , page table pages may...

CVE-2026-90269

CVE-2026-90269 affects the Linux kernel BPF subsystem. The verifier fails to rewrite BPF_LOAD_ACQ (load-acquire) into a BPF_PROBE_MEM load, unlike a regular BPF_LDX . As a result, the JIT emits a plain load with no exception-table entry, so a page fault on that load panics the kernel instead of b...

CVE-2026-90264 btrfs: always wait for ordered extents to avoid OE races

In the Linux kernel, the following vulnerability has been resolved: btrfs: always wait for ordered extents to avoid OE races BUG Syzbot reported a bug that there can be conflicting OEs for the same range: BTRFS critical device loop4: panic in insertorderedextent:264: overlapping ordered extents,...

CVE-2026-90264

CVE-2026-90264 is a race condition in the Linux kernel's btrfs filesystem that can cause a kernel BUG/panic . The bug occurs when a direct IO finishes short: the file's isize is reverted, which skips the ordered extent (OE) wait during subsequent buffered writeback. This allows a new OE to be ins...

CVE-2026-90192

CVE-2026-90192 affects the Linux kernel 's Qualcomm qcom-cpucp mailbox driver. The root cause is a NULL pointer dereference in qcom_cpucp_mbox_send_data(), which blindly dereferenced the data pointer when mailbox_clear_channel() invoked mbox_send_message() with NULL data to signal an RX channel c...

CVE-2026-90083

CVE-2026-90083 affects the Linux kernel's net/sched act_ife (IFE) traffic control action. The IFE action uses skb->dev->hard_header_len as the Ethernet header length, which is incorrect on non-Ethernet devices (e.g., PPP reports PPP_HDRLEN while nothing is stripped on ingress). When a packe...
