CVE-2023-52847: Linux kernel BTTV driver may crash after removal
CVE-2023-52847 · published 2 years ago
Summary
The BTTV video driver in several Ubuntu Linux builds can try to use memory that has already been freed when the driver is removed, potentially causing a system crash. This happens because a timer that was started when the driver loaded is not properly stopped before the driver is unloaded. Update to the latest kernel package for your Ubuntu cloud images (Azure, AWS, GCP, HWE, HWE Edge) to apply the fix.

Original advisory text
media: bttv: fix use after free error due to btv->timeout timer
In the Linux kernel, the following vulnerability has been resolved: media: bttv: fix use after free error due to btv->timeout timer There may be some a race condition between timer function bttv_irq_timeout and bttv_remove. The timer is setup in probe and there is no timer_delete operation in remove function. When it hit kfree btv, the function might still be invoked, which will cause use after free bug. This bug is found by static analysis, it may be false positive. Fix it by adding del_timer_sync invoking to the remove function. cpu0 cpu1 bttv_probe ->timer_setup ->bttv_set_dma ->mod_timer; bttv_remove ->kfree(btv); ->bttv_irq_timeout ->USE btv
