Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: inetdiag: fixed a kernel-infoleak issue for UDP sockets KMSAN reported a kernel-infoleak issue 1 that could be exploited by unprivileged users. After analysis, it turned out that UDP was not initializing r-idiagexpires. Other...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In mptcp, the task of cleaning up subflows has been moved to mptcpDestroyCommon. If the creation of a mptcp socket fails due to the CGROUPINETSOCKCREATE eBPF program, the MPTCP protocol ends up leaking all subflows. This related...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

There is a use-after-free vulnerability in the Linux Kernel that can be exploited to achieve local privilege escalation. To exploit this vulnerability, the CONFIGTLS or CONFIGXFRMESPINTCP kernel configuration flags must be set; however, the operation does not require any special privileges. There...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: fixed a memory leak in tcpconnrequest. If inetcskreqskqueuehashadd returns false, tcpconnrequest will return without freeing the dst memory, which was allocated in afops-routereq. Here is the stack trace for the issue:...

Astra Linux – Vulnerability in Linux, Linux 5.10

In ipcheckmcrcu of igmp.c, there is a potential use after free due to improper locking. This could lead to a local escalation of privileges when opening and closing inet sockets, without the need for additional execution privileges. User interaction is not required for exploitation. Product:...

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

In the Linux kernel, the following vulnerability has been resolved: inet: inetdefrag: prevent sk release while still in use The functions iplocalout and others can pass skb-sk as a function argument. If the skb is a fragment and reassembly occurs before such a function call returns, the sk must n...
