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 exuberant-ctags

A flaw was discovered in Exuberant Ctags regarding its handling of the "-o" option. This option specifies the tag filename. A specially crafted tag filename, specified either in the command line or in the configuration file, can lead to arbitrary command execution. This occurs because the...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: NFSv4/pnfs: A use-after-free bug has been fixed in open. If someone cancels the open RPC call, then we must not attempt to free either the open slot or the layoutget operation arguments, as they are likely still in use by the hun...

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

In the Linux kernel, the following vulnerability has been resolved: sched/ext: Prevent calls to updatelockedrq with a NULL rq. Avoid invoking updatelockedrq when the runqueue .rq pointer is NULL in the SCXCALLOP and SCXCALLOPRET macros. Previously, calling updatelockedrqNULL with preemption enabl...

In the Linux kernel, the following vulnerability has been resolved: phy: mdio: fix memory leak Syzbot reported a memory leak in the MDIO bus interface. The problem stemmed from incorrect state logic. The MDIOBUSALLOCATED state indicates two possible statuses: 1. The bus is only allocated. 2. The...

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...
