kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel
A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fixed a slow server-side memory leak caused by RPC-over-TCP. Jan Schunk reported that his small NFS servers experience memory exhaustion after just a few days. A bisect analysis shows that commit e18e157bb5c8 “SUNRPC:...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed the issue of loading the RxGK token to check bounds. The rxrpcpreparsexdryfsrxgk function reads the raw key length and ticket length from the XDR token as u32 values. It then rounds up each value by 4 before using th...
Astra Linux – Vulnerability in Linux 5.10, Linux
The SUNRPC subsystem in the Linux kernel, up to version 5.17.2, can call the xsxprtfree function before ensuring that the sockets are in the intended state...
Astra Linux – Vulnerability in Samba
An infinite loop vulnerability was discovered in Samba’s mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets sent by the client, the core unmarshalling function slunpackloop failed to validate a field in the network packet that contains the count of elements in an array-li...
Astra Linux – Vulnerability in Samba
A flaw was discovered in the way Samba implemented DCE/RPC. If a client to a Samba server sent a very large DCE/RPC request and chose to fragment it, an attacker could replace the later fragments with their own data, thereby bypassing the signature requirements...
Astra Linux – Vulnerability in Samba
A flaw was discovered in Samba’s DNS server. A authenticated user could exploit this flaw to cause damage to the RPC server. This RPC server, which also supports protocols other than dnsserver, will be restarted after a short delay. However, it is easy for an authenticated, non-administrative...
Astra Linux – Vulnerability in Linux 5.10
A race condition was detected in the Linux kernel’s RxRPC network protocol, during the processing of RxRPC bundles. This issue arises due to the lack of proper locking when performing operations on an object. This could allow an attacker to escalate privileges and execute arbitrary code within th...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed an issue where the buffer was overread in rxgkdoverifyauthenticator. Fixed rxgkdoverifyauthenticator to check the buffer size before checking the nonce...
Astra Linux – Vulnerability in Samba
A Type Confusion vulnerability was discovered in Samba’s mdssvc RPC service for Spotlight. When parsing Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary, where the keys are character strings, and the values can be any of the supported types in the mdssvc...
Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15
In the Linux kernel, the following vulnerabilities have been resolved: SUNRPC: Fixed a server shutdown leak A race condition was addressed where kthreadstop might prevent threadfn from being called at all. If this occurs, the svcrqst will not be cleaned up properly...
Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15
In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fixed an UAF in svctcplistendataready After the listener svcsock is freed, and before invoking svctcpaccept for the established child sock, there is a window during which the newsock may retain the freed listener svcsock ...
Astra Linux – Vulnerability in Linux 5.10, Linux
In the Linux kernel, the following vulnerabilities have been resolved: rxrpc: Fixed the issue where the listen function sets the backlog to too high for preallocation rings. The listen handler of AFRXRPC allows you to set the backlog to 32 if you increase the sysctl value. However, since the...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fixed the issue where the timer for starting a call race against the destruction of the call occurred. The rxrpccall structure contains a timer used to handle various timed events related to a call. This timer can be...

A issue was discovered in Das U-Boot during the period from 2019.07. There is a stack-based buffer overflow in the nfshandler reply helper function: rpclookupreply...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: rxrpc: Only drop the call reference if one was actually acquired. The function rxrpcinputpacketonconn can process a packet for the client after the current client call on the channel has already been terminated. In this case,...
