CVE-2024-53150 – ALSA: usb-audio: Fix out of bounds reads when finding clock sources

24 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix out of bounds reads when finding clock sources The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is ... • https://git.kernel.org/stable/c/a632bdcb359fd8145e86486ff8612da98e239acd •
CVE-2024-53148 – comedi: Flush partial mappings in error case

24 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: comedi: Flush partial mappings in error case If some remap_pfn_range() calls succeeded before one failed, we still have buffer pages mapped into the userspace page tables when we drop the buffer reference with comedi_buf_map_put(bm). The userspace mappings are only cleaned up later in the mmap error path. Fix it by explicitly flushing all mappings in our VMA on the error path.

CVE-2024-53146 – NFSD: Prevent a potential integer overflow
https://notcve.org/view.php?id=CVE-2024-53146
24 Dec 2024 — In the Linux kernel, the following vulnerability has been resolved: NFSD: Prevent a potential integer overflow If the tag length is >= U32_MAX - 3 then the "length + 4" addition can result in an integer overflow. Address this by splitting the decoding into several steps so that decode_cb_compound4res() does not have to perform arithmetic on the unsafe length value. • https://git.kernel.org/stable/c/745f7ce5a95e783ba62fe774325829466aec2aa8 •
