Linux · Linux Kernel · CVE-2019-19769
Name of the Vulnerable Software and Affected Versions:
Linux kernel version 5.3.10
Description:
The issue is related to a use-after-free in the `perf trace lock acquire` function, which can lead to a denial of service. Additionally, there is a possible out of bounds write due to a use after free in the ` locks wake up blocks` function of `locks.c`, which could result in local escalation of privilege with no additional execution privileges needed. User interaction is not required for exploitation.
Recommendations:
For Linux kernel version 5.3.10, consider disabling the `perf trace lock acquire` function as a temporary workaround until a patch is available.
Restrict access to the `locks.c` module to minimize the risk of exploitation.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
