CVE-2024-40968 is fixed in 19 products on 1 platform, first by DEBIAN-CVE-2024-40968, released July 12, 2024. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2024-40968 - Priority: Routine - CVSS: 5.5 (medium) - EPSS: 0.0030 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Jul 12, 2024 ## Description In the Linux kernel, the following vulnerability has been resolved: MIPS: Octeon: Add PCIe link status check The standard PCIe configuration read-write interface is used to access the configuration space of the peripheral PCIe devices of the mips processor after the PCIe link surprise down, it can generate kernel panic caused by "Data bus error". So it is necessary to add PCIe link status check for system protection. When the PCIe link is down or in training, assigning a value of 0 to the configuration address can prevent read-write behavior to the configuration space of peripheral PCIe devices, thereby preventing kernel panic. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | bpftool ol 8 | 0:5.15.0-210.163.7.el9uek |
