In the Linux kernel, the following vulnerability has been resolved: xsk: Added a missing overflow check in xdpumemreg. The number of chunks can exceed the range of u32. Ensure that -EINVAL is returned in case of an overflow. Additionally, removed a redundant u32 cast when assigning umem-npgs...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: stmmac: A possible memory leak has been fixed in stmmacdvrprobe. The bitmapfree function should be called to release priv-afxdpzcqps when createsinglethreadworkqueue fails. Otherwise, a memory leak will occur. Therefore, we...

CVE-2026-81002

A flaw was found in the Linux kernel's XDP eXpress Data Path component. Incorrect handling of zero-copy frame layout in the xdpconvertzctoxdpframe function can allow an AFXDP zero-copy packet, when redirected through cpumap, to cause a memory corruption. This can lead to a slab-out-of-bounds erro...
