CVE-2024-53197Exploited in the wildNVD status: Analyzed

Linux Kernel Out-of-Bounds Access

Published Updated By the CyberSecBulletin desk

CVE-2024-53197 is a high-severity out-of-bounds write vulnerability in Linux, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists versions 0b4ea4bfe16566b84645ded1403756a2dc4e0f19, 9b8460a2a7ce478e0b625af7c56d444dc24190f7, 62dc01c83fa71e10446ee4c31e0e3d5d1291e865 as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on April 9, 2025, which means attacks have been observed in the wild.

Patch now

Attackers are already exploiting this vulnerability, according to CISA.

What to do

  1. Update Linux to 0b4ea4bfe16566b84645ded1403756a2dc4e0f19 or 9b8460a2a7ce478e0b625af7c56d444dc24190f7 or 62dc01c83fa71e10446ee4c31e0e3d5d1291e865 or 9887d859cd60727432a01564e8f91302d361b72b, whichever matches your release line, or a later version.
  2. Update Linux Kernel to 4.19.325 or 5.4.287 or 5.10.231 or 5.15.174, whichever matches your release line, or a later version.
  3. CISA's required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.

Official description

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential out-of-bound accesses for Extigy and Mbox devices A bogus device can provide a bNumConfigurations value that exceeds the initial value used in usb_get_configuration for allocating dev->config. This can lead to out-of-bounds accesses later, e.g. in usb_destroy_configuration.

The underlying weakness: Out-of-bounds Write

The product writes data past the end, or before the beginning, of the intended buffer.

How developers prevent this class of flaw

  • Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow protection, but the protection can be disabled by the programmer. Be wary that a language's interface to native code may still be subject to overflows, even if the language itself is theoretically safe.
  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. Examples include the Safe C String Library (SafeStr) by Messier and Viega, and the Strsafe.h library from Microsoft. These libraries provide safer versions of overflow-prone string-handling functions.
  • Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking. D3-SFCV (Stack Frame Canary Validation) from D3FEND discusses canary-based detection in detail.
