  script_tag(name:"insight", value:"Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

CVE-2018-13093, CVE-2018-13094 Wen Xu from SSLab at Gatech reported several NULL pointer dereference flaws that may be triggered when mounting and operating a crafted XFS volume. An attacker able to mount arbitrary XFS volumes could use this to cause a denial of service (crash).

CVE-2018-20976

It was discovered that the XFS file-system implementation did not correctly handle some mount failure conditions, which could lead to a use-after-free. The security impact of this is unclear.

CVE-2018-21008

It was discovered that the rsi wifi driver did not correctly handle some failure conditions, which could lead to a use-after free. The security impact of this is unclear.

CVE-2019-0136

It was discovered that the wifi soft-MAC implementation (mac80211) did not properly authenticate Tunneled Direct Link Setup (TDLS) messages. A nearby attacker could use this for denial of service (loss of wifi connectivity).

CVE-2019-2215

The syzkaller tool discovered a use-after-free vulnerability in the Android binder driver. A local user on a system with this driver enabled could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. However, this driver is not enabled on Debian packaged kernels.

CVE-2019-10220

Various developers and researchers found that if a crafted file system or malicious file server presented a directory with filenames including a '/' character, this could confuse and possibly defeat security checks in applications that read the directory.

The kernel will now return an error when reading such a directory, rather than passing the invalid filenames on to user-space.

CVE-2019-14615

It was discovered that Intel 9th and 10th generation GPUs did not clear user-visible state during a context switch, which resulted in information leaks between GPU tasks. This has been mitigated in the i915 driver.

The affected chips (gen9 and gen10) are listed at .

CVE-2019-14814, CVE-2019-14815, CVE-2019-14816 Multiple bugs were discovered in the mwifiex wifi driver, which could lead to heap buffer overflows. A local user permitted to configure a device handled by this driver could probably use this for privilege escalation.

CVE-2019-14895, CVE-2019-14901 ADLab of Venustech discovered potential heap buffer overflows in the mwifiex wifi driver. On systems using this driver, a malicious Wireless Access Point or adhoc/P2P peer could use these to cause a denial of service (memory corruption or crash) or possibly for remote code execution.

CVE-2019-14896, CVE-2019-14897 ADLab of Venustech discovered potential heap and stack buffer overflows in the libertas wifi driver. On systems using this driver, a malicious Wireless Access Point or adhoc/P2P peer could use these to cause a denial of ... [Please see the references for more information on the vulnerabilities]");
