Linux: Out-of-bounds Read
CVE-2024-52332 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 4458046617dfadc351162dbaea1945c57eebdf36, e0155b1b1509d0ef4799bd1cd73309ca466df3f3, 4fe517643f529e805bb6b890a4331c100e8f2484 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 4458046617dfadc351162dbaea1945c57eebdf36 or e0155b1b1509d0ef4799bd1cd73309ca466df3f3 or 4fe517643f529e805bb6b890a4331c100e8f2484 or 8009cdcc493fa30d4572016daf2d6999da4d6c54, whichever matches your release line, or a later version.
- Update SIMATIC S7-1500 CPU 1518-4 PN/DP MFP to V3.1.5 or a later version.
- Update SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP to V3.1.5 or a later version.

Official description
In the Linux kernel, the following vulnerability has been resolved: igb: Fix potential invalid memory access in igb_init_module() The pci_register_driver() can fail and when this happened, the dca_notifier needs to be unregistered, otherwise the dca_notifier can be called when igb fails to install, resulting to invalid memory access.

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.
- Record last changed materially (score, affected products, status or references).
