CVE-2023-53318 Details
Description
In the Linux kernel, the following vulnerability has been resolved: recordmcount: Fix memory leaks in the uwrite function Common realloc mistake: 'file_append' nulled but not freed upon failure
A memory leak vulnerability has been identified in the Linux kernel's recordmcount feature, specifically within the uwrite function. This issue arises from a common mistake in memory management: the 'file_append' variable is set to null but not properly freed when a realloc operation fails. As a result, the memory allocated to 'file_append' is not released, leading to a leak.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. Instructions for downloading the latest kernel version can be found on the official Linux kernel website.
