Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: wlcore – Ensure skbheadroom before calling skbpush. This fix prevents occasional skbunderpanic errors in wl1271txwork. In this case, the allocated headroom is less than what is actually needed typically 110 – 94 = 16 bytes...

CVE-2026-53217

The CVE-2026-53217 issue affects the Linux kernel MVPP2 driver: RX data was synchronized at the hardware packet offset, leaving end-of-frame data possibly stale on non‑coherent DMA. Root cause is incorrect DMA sync range (starting at dma_addr and not covering the actual written packet tail). The ...

CVE-2025-71222

In the Linux kernel, the following vulnerability has been resolved: wifi: wlcore: ensure skb headroom before skbpush This avoids occasional skbunderpanic Oops from wl1271txwork. In this case, headroom is less than needed typically 110 - 94 = 16 bytes...

CVE-2025-71222

CVE-2025-71222 (Linux kernel) : Affects the wifi wlcore path. The issue arises from an insufficient skb headroom check before skb_push, causing an skb_under_panic Oops in wl1271_tx_work when headroom is insufficient (typical 110 vs 94, leaving 16 bytes). The fix ensures proper headroom before skb...

CVE-2025-71098 ip6_gre: make ip6gre_header() robust

In the Linux kernel, the following vulnerability has been resolved: ip6gre: make ip6greheader robust Over the years, syzbot found many ways to crash the kernel in ip6greheader 1. This involves team or bonding drivers ability to dynamically change their dev-neededheadroom and/or dev-hardheaderlen ...

CVE-2023-53785

CVE-2023-53785 : In MT76 MT7921/MT7921_USB_SDIO path, code assumed adequate headroom in an skb when prepending SDIO headers, which could trigger kernel panics if the skb came from a non-net-core path (e.g., bridged interfaces). The fix adds a skb_cow_head() call in mt7921_usb_sdio_tx_prepare_skb(...
