In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/qcom/lmh: Check for SCM availability at probe Up until now, the necessary scm availability check has not been performed, leading to possible null pointer dereferences (which did happen for me on RB1).

https://notcve.org/view.php?id=CVE-2024-39464
In the Linux kernel, the following vulnerability has been resolved: media: v4l: async: Fix notifier list entry init struct v4l2_async_notifier has several list_head members, but only waiting_list and done_list are initialized. notifier_entry was kept 'zeroed' leading to an uninitialized list_head. This results in a NULL-pointer dereference if csi2_async_register() fails, e.g. node for remote endpoint is disabled, and returns -ENOTCONN. The following calls to v4l2_async_nf_unregister() results in a NULL pointer dereference. Add the missing list head initializer. • https://git.kernel.org/stable/c/b8ec754ae4c563f6aab8c0cb47aeb2eae67f1da3 https://git.kernel.org/stable/c/a80d1da923f671c1e6a14e8417cd2f117b27a442 https://git.kernel.org/stable/c/44f6d619c30f0c65fcdd2b6eba70fdb4460d87ad https://git.kernel.org/stable/c/6d8acd02c4c6a8f917eefac1de2e035521ca119d •
