In the Linux kernel, the following vulnerability has been resolved: staticcall: The unnecessary WARNON call in staticcallmodulenotify should be replaced. staticcallmodulenotify triggers a WARNON when memory allocation fails in staticcalladdmodule. This approach isn’t really justified, because the...

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: sched/scs: The task stack state is reset in bringupcpu. When a CPU is hot-plugged, the idle task on that CPU calls several layers of C code before finally leaving the kernel. When KASAN is in use, a “poisoned” shadow is left behi...
Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15
In the drivers/video/fbdev/smscufx.c file within the Linux kernel, up to version 5.19.12, there is a race condition that can lead to a use-after-free if a physically nearby attacker removes a USB device while the open function is called. This issue is essentially a race condition between ufxopsop...

In the Linux kernel, the following vulnerability has been resolved: liquidio: The handling of NULL pointers in liovfrepcopypacket was adjusted. In liovfrepcopypacket, pginfo-page is compared to a NULL value, but it is then unconditionally passed to skbaddrxfrag, which seems strange and could lead...
Astra Linux – Vulnerability in WebKit2GTK
A logic issue in the handling of concurrent media has been addressed through improved state management. This issue is fixed in macOS Monterey 12.4, iOS 15.5, and iPadOS 15.5. Video self-preview in a webRTC call may be interrupted if the user answers a phone call...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fixed the jump offset calculation in tailcall. The additional call to bpfintjitcompile skips the JIT context initialization. This effectively skips the offset calculation, resulting in outoffset = -1. Therefore, t...
