In the Linux kernel, the following vulnerability has been resolved: dm mirror log: The bitsetsize is rounded up to BITSPERLONG. The code in dm-log rounds up bitsetsize to 32 bits. Then, it uses findnextzerobitle on the allocated region. findnextzerobitle accesses the bitmap using unsigned long...

Astra Linux – Vulnerability in Golang-logrus

There is a denial-of-service vulnerability in github.com/sirupsen/logrus when using Entry.Writer to log a single-line payload larger than 64KB without newline characters. Due to limitations in the internal bufio.Scanner, the read operation fails with “token too long”, and the writer pipe is close...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: lib/generic-radix-tree.c: Do not cause overflow in the peek function.

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: arm64: ftrace: consistently handles PLTs. Sometimes it is necessary to use a PLT entry to call a ftrace trampoline. This is handled by ftracemakecall and ftracemakenop, both of which have almost identical logic. However, this is...

Astra Linux – Vulnerability in glib2.0

A issue was discovered in GNOME GLib before versions 2.66.7 and 2.67.x before version 2.67.4. If the gbytearraynewtake function was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2^32, resulting in unintended length truncation...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/hfi1: Fixed potential integer multiplication overflow errors. When multiplying values of different types, an overflow can occur even when storing the result in a larger type. This happens because the conversion is perform...

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

In the Linux kernel, the following vulnerability has been resolved: EDAC/bluefield: Fixed potential integer overflows. The 64-bit argument for the “get DIMM info” SMC call consists of memctrlidx, which is left-shifted by 16 bits and OR-ed with the DIMM index. Since memctrlidx is defined as a 32-b...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: blk-throttle: prevented overflow during the calculation of wait time. There is a problem identified during code review in tgwithinbpslimit; the expression 'bpslimit jiffyelapsedrnd' might cause an overflow. This issue can be...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: media: ar0521 – No overflow occurs when checking PLL values. According to Coverity reports, the PLL checks compare 64-bit integers with 32-bit ones. Depending on the values of the variables, this may lead to underflow. The issue...

Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: tty: ttybuffer: Fixed the soft lockup issue in flushtoldisc. When running the ltp testcase ltp/testcases/kernel/pty/pty04.c with arm64, there is a soft lockup. The detailed call trace is as follows: Workqueue: eventsunbound →...

In the Linux kernel, the following vulnerability has been resolved: x86/MCE/AMD: Use a u64 type for the bankmap. The maximum number of MCA banks is 64 MAXNRBANKS; see a0bc32b3cacf “x86/mce: Increase the maximum number of banks to 64”. However, the bankmap, which contains a bitfield indicating whi...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Fixed an out-of-bounds access in rpage. When PAGESIZE is 64K, if logreadrst calls readlogpage for the first time, the size of buffer will be equal to DefaultLogPageSize4K. However, for buffer operations like memcpy, if...
