26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: media: davinci: vpif: fix use-after-free on driver unbind The driver allocates and registers two platform device structures during probe, but the devices were never deregistered on driver unbind. This results in a use-after-free on driver unbind as the device structures were allocated using devres and would be freed by driver core when remove() returns. Fix this by adding the missing deregistration calls to the remove() callback and failing... • https://git.kernel.org/stable/c/479f7a1181058689435baddc16a6a42e1a8ff0e8 •

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: soc: qcom: rpmpd: Check for null return of devm_kcalloc Because of the possible failure of the allocation, data->domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better to check it and directly return -ENOMEM without releasing data manually if fails, because the comment of the devm_kmalloc() says "Memory allocated with this function is automatically freed on driver detach.". • https://git.kernel.org/stable/c/bbe3a66c3f5a65fb3d702351bac2a6033944d389 •

https://notcve.org/view.php?id=CVE-2021-47649
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: udmabuf: validate ubuf->pagecount Syzbot has reported GPF in sg_alloc_append_table_from_pages(). The problem was in ubuf->pages == ZERO_PTR. ubuf->pagecount is calculated from arguments passed from user-space. If user creates udmabuf with list.size == 0 then ubuf->pagecount will be also equal to zero; it causes kmalloc_array() to return ZERO_PTR. Fix it by validating ubuf->pagecount before passing it to kmalloc_array(). • https://git.kernel.org/stable/c/fbb0de795078190a9834b3409e4b009cfb18a6d4 •
