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

In the Linux kernel, the following vulnerabilities have been resolved: - net: hsr: Avoid potential out-of-bound access in fillframeinfo. syzbot can inject a packet with 14 bytes, pretending it is a VLAN packet. Since fillframeinfo already relies on skb-maclen, extend the check to cover this case....

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net/smc: It was fixed that link down work might be scheduled before lgr is freed, but it would execute after lgr is freed, which could lead to a crash. Therefore, it is necessary to hold a reference before scheduling the link dow...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: NFS: Fixed a potential buffer overflow in nfssysfslinkrpcclient. The name field is defined as char64, and the size of clnt-clprogram-name remains unknown. Invoking strcat directly will also lead to a potential buffer overflow...

In the Linux kernel, the following vulnerabilities have been resolved: gtp: The device is destroyed along with the udp socket’s netns. The gtpnewlink function links the device to the list in devnet dev, instead of srcnet, where an udp tunnel socket is created. Even when srcnet is removed, the...

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

In the Linux kernel, the following vulnerability has been resolved: NFSD: fixed a hang issue in nfsd4shutdowncallback. If nfs4client is in the courtesy state, there is no point in sending the callback. This causes nfsd4shutdowncallback to hang, as clcbinflight is not set to 0. This hang lasts...

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

In the Linux kernel, the following vulnerability has been resolved: nfsd: When trying to queue dlrecall, if the call to nfsd4runcb fails, the reference count of dlstid is not decremented. This leads to a memory leak as follows: Unreferenced object 0xffff88812067b578 size 344: Comm “nfsd”, pid 276...
