Publication date: 2025-12-30

Last updated on: 2025-12-30

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: media: s5p-mfc: Clear workbit to handle error condition During error on CLOSE_INSTANCE command, ctx_work_bits was not getting cleared. During consequent mfc execution NULL pointer dereferencing of this context led to kernel panic. This patch fixes this issue by making sure to clear ctx_work_bits always.

Executive Summary

This vulnerability occurs in the Linux kernel's media s5p-mfc component. When an error happens during the CLOSE_INSTANCE command, a variable called ctx_work_bits was not cleared properly. This caused a NULL pointer dereference in subsequent executions, leading to a kernel panic (system crash). The fix ensures that ctx_work_bits is always cleared to prevent this issue.

Impact Analysis

This vulnerability can cause the Linux kernel to panic and crash due to a NULL pointer dereference in the media s5p-mfc component. This can lead to system instability, downtime, and potential loss of data or service availability.
