AI-suggested
A patch is available and has been released by the vendor. Users should update their linux-aws kernel packages to versions 5.15.0-1111.118~20.04.1 or later (and the other specified fixed versions) to resolve the memory leak issue. After updating, a system reboot is required to apply the kernel fixes. No additional mitigation steps are indicated by the vendor advisory.
Description
A memory leak vulnerability was identified and resolved in the Linux kernel's x86 platform driver toshiba_haps. The issue involved improper handling of allocated memory in the add and remove routines, causing memory leaks. This vulnerability affects the linux-aws kernel versions prior to certain 5.15.x releases. The issue has been fixed by updating the kernel to versions that use devm_kzalloc() for memory allocation to prevent leaks. This vulnerability is part of a broader set of Linux kernel security fixes addressing multiple subsystems. No known exploits are reported in the wild for this specific issue.
