Linux: Out-of-bounds Read

Published Updated By the CyberSecBulletin desk

CVE-2024-58007 is a high-severity out-of-bounds read vulnerability in Linux, with a CVSS 3.1 base score of 7.1 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 7445fa05317534bbd8b373c0eff8319187916030, 2495c6598731b6d7f565140f2bd63ef4bc36ce7d, 2d09d3c9afa2fc422ac3df7c9b8534f350ee19dd as the first without the flaw, so updating Linux to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.25% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Linux to 7445fa05317534bbd8b373c0eff8319187916030 or 2495c6598731b6d7f565140f2bd63ef4bc36ce7d or 2d09d3c9afa2fc422ac3df7c9b8534f350ee19dd or 9c88b3a3fae4d60641c3a45be66269d00eff33cd, whichever matches your release line, or a later version.
  2. Update Linux Kernel to 6.1.129 or 6.6.78 or 6.12.14 or 6.13.3, whichever matches your release line, or a later version.

Official description

In the Linux kernel, the following vulnerability has been resolved: soc: qcom: socinfo: Avoid out of bounds read of serial number On MSM8916 devices, the serial number exposed in sysfs is constant and does not change across individual devices. It's always: db410c:/sys/devices/soc0$ cat serial_number 2644893864 The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not have support for the serial_num field in the socinfo struct. There is an existing check to avoid exposing the serial number in that case, but it's not correct: When checking the item_size returned by SMEM, we need to make sure the *end* of the serial_num is within bounds, instead of comparing with the *start* offset. The serial_number currently exposed on MSM8916 devices is just an out of bounds read of whatever comes after the socinfo struct in SMEM. Fix this by changing offsetof() to offsetofend(), so that the size of the field is also taken into account.

The underlying weakness: Out-of-bounds Read

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

How developers prevent this class of flaw

  • Use a language that provides appropriate memory abstractions.
