CVSS Release:
CVE-2024-27063: In the Linux kernel, the following vulnerability has been resolved: leds: trigger: netdev: Fix kernel panic on interface rename trig notify Commit d5e01266e7f5 ("leds: trigger: netdev: add additional specific link speed mode") in the various changes, reworked the way to set the LINKUP mode in commit cee4bd16c319 ("leds: trigger: netdev: Recheck NETDEV_LED_MODE_LINKUP on dev rename") and moved it to a generic function. This changed the logic where, in the previous implementation the dev from the trigger event was used to check if the carrier was ok, but in the new implementation with the generic function, the dev in trigger_data is used instead. This is problematic and cause a possible kernel panic due to the fact that the dev in the trigger_data still reference the old one as the new one (passed from the trigger event) still has to be hold and saved in the trigger_data struct (done in the NETDEV_REGISTER case). On calling of get_device_state(), an invalid net_dev is used and this cause a kernel panic. To handle this correctly, move the call to get_device_state() after the new net_dev is correctly set in trigger_data (in the NETDEV_REGISTER case) and correctly parse the new dev.
The exploitability of CVE-2024-27063 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
No exploitability data is available for CVE-2024-27063.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2024-27063, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2024-27063, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.045% (probability of exploit)
EPSS Percentile: 18.35%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 81.65% of others.
