In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211hwsim: dropping short frames Technically, some control frames, such as ACK frames, are shorter and end after “Address 1”. Such frames should not be forwarded through wmediumd or similar user-space mechanisms...

Astra Linux – Vulnerability in Nasm

There is an illegal address access in asm/preproc.c function: ismmacro within Netwide Assembler NASM 2.14rc16. This issue may lead to a denial of service due to out-of-bounds array access, as a certain conversion can result in a negative integer...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: octeonep: fixed a potential memory leak in octepdevicesetup. When errors such as unsupporteddev and mbox init occur, the variables oct-conf and iounmap oct-mmioi.hwaddr were not freed properly. This could lead to a memory leak...

Astra Linux – Vulnerability in Linux 5.10

The checkaluop function in kernel/bpf/verifier.c in the Linux kernel, as of v5.16-rc5, did not properly update the bounds when handling the mov32 instruction. This issue allows local users to obtain potentially sensitive address information, also known as a “pointer leak.”...

In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: Fixed the refcount leak in the address translation for armsmmudevice. The reference counting issue occurs in several exception handling paths of armsmmuiovatophyshard. When these error scenarios occur, the functio...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: ntfs: check for overflow when iterating ATTRRECORDs The kernel iterates over ATTRRECORDS in mft records in the ntfsattrfind function. Since ATTRRECORDS are adjacent to each other, the kernel can access the next ATTRRECORD from th...

Astra Linux – Vulnerability in RustC

The library/std/src/net/parser.rs file in Rust before version 1.53.0 does not properly handle zero characters at the beginning of an IP address string. In some cases, this allows attackers to bypass access controls based on IP addresses due to incorrect octal interpretation of these characters...
