Linux · Linux Kernel · CVE-2010-4242
**Name of the Vulnerable Software and Affected Versions**
Linux kernel version 2.6.36
Linux kernel versions 2.6.9
**Description**
The issue is related to the Linux kernel, specifically the HCI UART driver, where the hci uart tty open function does not verify whether the tty has a write operation. This allows local users to cause a denial of service via vectors related to the Bluetooth driver. Additionally, multiple vulnerabilities have been identified in various Linux kernel packages, including kernel-devel, kernel-doc, kernel-hugemem, kernel-largesmp, and kernel-smp, which can lead to confidentiality, integrity, and availability breaches. These vulnerabilities can be exploited remotely.
**Recommendations**
For Linux kernel version 2.6.36, consider disabling the hci uart tty open function as a temporary workaround until a patch is available.
For Linux kernel versions 2.6.9, restrict access to the vulnerable kernel packages to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
