Summary

linux-oem-5.13 vulnerabilities

Details

It was discovered that the btrfs file system in the Linux kernel did not properly handle removing a non-existent device id. An attacker with CAPSYSADMIN could use this to cause a denial of service. (CVE-2021-3739)

It was discovered that the Qualcomm IPC Router protocol implementation in the Linux kernel did not properly validate metadata in some situations. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2021-3743)

It was discovered that the virtual terminal (vt) device implementation in the Linux kernel contained a race condition in its ioctl handling that led to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information. (CVE-2021-3753)

It was discovered that the Linux kernel did not properly account for the memory usage of certain IPC objects. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2021-3759)
