CVE-2026-43132 Details
Description
In the Linux kernel, the following vulnerability has been resolved: dm-verity: correctly handle dm_bufio_client_create() failure If either of the calls to dm_bufio_client_create() in verity_fec_ctr() fails, then dm_bufio_client_destroy() is later called with an ERR_PTR() argument. That causes a crash. Fix this.
A vulnerability in the Linux kernel's dm-verity component can lead to a system crash. This issue arises when the function 'dm_bufio_client_create()' fails during the creation of buffer clients for error correction. The failure is not properly managed, causing 'dm_bufio_client_destroy()' to be called with an invalid argument, which triggers a crash. This vulnerability affects the Linux kernel stable tree.
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 available in the Linux kernel stable tree.
