CVE-2022-50384 Details
Description
In the Linux kernel, the following vulnerability has been resolved: staging: vme_user: Fix possible UAF in tsi148_dma_list_add Smatch report warning as follows: drivers/staging/vme_user/vme_tsi148.c:1757 tsi148_dma_list_add() warn: '&entry->list' not removed from list In tsi148_dma_list_add(), the error path "goto err_dma" will not remove entry->list from list->entries, but entry will be freed, then list traversal may cause UAF. Fix by removeing it from list->entries before free().
A use-after-free vulnerability has been identified in the Linux kernel's staging area, specifically within the VME user driver. The issue arises in the TSI148 DMA list add function, where an entry's list is not properly removed before the entry is freed. This oversight can lead to a use-after-free condition during list traversal. The vulnerability affects several versions of the Linux kernel.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the official Linux kernel website.
