Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In the xskmapdeleteelem function, an unsigned integer map-maxentries is compared with a user-controlled signed integer k. Due to implicit type conversion, a large unsigned value for map-maxEntries can bypass the intended bounds...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xsk: Fixed an use-after-free error during socket cleanup. A use-after-free error can occur if the xskdiag interface is used after the socket has been unbound from the device. This can happen either due to the socket being closed ...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xsk: fixed the refcount underflow in the error path. This fix addresses a refcount underflow issue reported by syzbot, which can occur when the system runs out of memory. If xpalloctxdescs fails—and it can only fail due to...

CVE-2026-74707

A flaw was found in the Linux kernel's xsk AFXDP sockets component. This vulnerability allows a local user to bypass security validation by modifying transmission TX metadata after it has been initially checked but before it is used to prepare hardware requests. This could lead to unexpected syst...
