Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sockmap: Added a condresched function in sockhashfree. Several reports of syzbot soft lockups involve sockhashfree. If a map with a large number of buckets is destroyed, we need to yield the CPU when necessary...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sockmap: Avoid a race condition between sockmapclose and skpsockput. skpsockget will return NULL if the reference count of psock reaches 0, which will happen when the last call to skpsockput is completed. However, skpsockdrop may...

The vulnerability of the sock_map component in the Linux operating system’s kernel allows a hacker to cause a service failure.

The vulnerability of the sockmap component in the Linux operating system’s kernel is related to the assignment of the NULL pointer in the function sockmapclose. Exploiting this vulnerability can allow an attacker to cause a service failure...

The vulnerability of the sock_map_{close,destroy,unhash}() functions in the Linux operating system allows a hacker to compromise the confidentiality and accessibility of the protected information.

The vulnerability of the functions sockmapclose,destroy,unhash in the net/core/sockmap.c module of the Linux operating system is related to stack overflow due to infinite recursion. Exploiting this vulnerability can allow a remote attacker to compromise the confidentiality and accessibility of th...
