| Vetor | AV:N/AC:L/Au:N/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.3.11
Description
The issue is related to a memory leak in the
rsi send beacon() function, located in drivers/net/wireless/rsi/rsi 91x mgmt.c. This leak can be triggered by causing rsi prepare beacon() failures, potentially allowing a remote attacker to consume system memory, leading to a denial of service.Recommendations
For Linux kernel versions prior to 5.3.11, update to version 5.3.11 or later to resolve the issue.
As a temporary workaround, consider restricting access to the
rsi send beacon() function to minimize the risk of exploitation.Correção
