https://notcve.org/view.php?id=CVE-2021-47211
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: fix null pointer dereference on pointer cs_desc The pointer cs_desc return from snd_usb_find_clock_source could be null, so there is a potential null pointer dereference issue. Fix this by adding a null check before dereference. • https://git.kernel.org/stable/c/58fa50de595f152900594c28ec9915c169643739 https://git.kernel.org/stable/c/b97053df0f04747c3c1e021ecbe99db675342954 •

CVSS: -EPSS: 0%CPEs: 2EXPL: 0CVE-2021-47205 – clk: sunxi-ng: Unregister clocks/resets when unbinding
https://notcve.org/view.php?id=CVE-2021-47205
In the Linux kernel, the following vulnerability has been resolved: clk: sunxi-ng: Unregister clocks/resets when unbinding Currently, unbinding a CCU driver unmaps the device's MMIO region, while leaving its clocks/resets and their providers registered. This can cause a page fault later when some clock operation tries to perform MMIO. Fix this by separating the CCU initialization from the memory allocation, and then using a devres callback to unregister the clocks and resets. This also fixes a memory leak of the `struct ccu_reset`, and uses the correct owner (the specific platform driver) for the clocks and resets. Early OF clock providers are never unregistered, and limited error handling is possible, so they are mostly unchanged. The error reporting is made more consistent by moving the message inside of_sunxi_ccu_probe. • https://git.kernel.org/stable/c/b5dd513daa70ee8f6d281a20bd28485ee9bb7db2 https://git.kernel.org/stable/c/9bec2b9c6134052994115d2d3374e96f2ccb9b9d •
