| Vetor | AV:P/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.2.9
Description
The issue is related to a race condition and resultant use-after-free in the Linux kernel, specifically in the drivers/net/ethernet/qualcomm/emac/emac.c module. This occurs when a physically proximate attacker unplugs an emac based device, potentially allowing the attacker to impact the confidentiality, integrity, and availability of protected information. The vulnerability is associated with the emac remove() function.
Recommendations
For Linux kernel versions prior to 6.2.9, update to version 6.2.9 or later to resolve the issue.
As a temporary workaround, consider restricting access to the emac module to minimize the risk of exploitation.
