Linux: Out-of-bounds Read
CVE-2024-53162 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 05c9a7a5344425860202a8f3efea4d8ed2d10edb, e69d2845aaa080960f38761f78fd25aa856620c6, 700852528fc5295897d6089eea0656d67f9b9d88 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 0.26% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Linux to 05c9a7a5344425860202a8f3efea4d8ed2d10edb or e69d2845aaa080960f38761f78fd25aa856620c6 or 700852528fc5295897d6089eea0656d67f9b9d88 or 475b5098043eef6e72751aadeab687992a5b63d1, whichever matches your release line, or a later version.
- Update Linux Kernel to 6.6.64 or 6.11.11 or 6.12.2, whichever matches your release line, or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: crypto: qat/qat_4xxx - fix off by one in uof_get_name() The fw_objs[] array has "num_objs" elements so the > needs to be >= to prevent an out of bounds read.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
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.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
