CVE-2023-53449 Details
Description
In the Linux kernel, the following vulnerability has been resolved: s390/dasd: Fix potential memleak in dasd_eckd_init() `dasd_reserve_req` is allocated before `dasd_vol_info_req`, and it also needs to be freed before the error returns, just like the other cases in this function.
A memory leak vulnerability has been identified in the Linux kernel's s390/dasd component, specifically within the dasd_eckd_init() function. The issue arises because the dasd_reserve_req allocation is not properly managed before an error return, leading to a potential memory leak. This vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been addressed. The specific commit that resolves this issue is 460e9bed82e49db1b823dcb4e421783854d86c40.
