CVE-2023-52486 – drm: Don't unref the same fb many times by mistake due to deadlock handling
https://notcve.org/view.php?id=CVE-2023-52486
29 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: drm: Don't unref the same fb many times by mistake due to deadlock handling If we get a deadlock after the fb lookup in drm_mode_page_flip_ioctl() we proceed to unref the fb and then retry the whole thing from the top. But we forget to reset the fb pointer back to NULL, and so if we then get another error during the retry, before the fb lookup, we proceed the unref the same fb again without having gotten another reference. The end result is... • https://git.kernel.org/stable/c/376e21a9e4c2c63ee5d8d3aa74be5082c3882229 • CWE-833: Deadlock •

29 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Wake DMCUB before sending a command [Why] We can hang in place trying to send commands when the DMCUB isn't powered on. [How] For functions that execute within a DC context or DC lock we can wrap the direct calls to dm_execute_dmub_cmd/list with code that exits idle power optimizations and reallows once we're done with the command submission on success. For DM direct submissions the DM will need to manage the enter/exit seq... • https://git.kernel.org/stable/c/303197775a97416b62d4da69280d0c120a20e009 •

CVE-2023-52483 – mctp: perform route lookups under a RCU read-side lock

29 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: mctp: perform route lookups under a RCU read-side lock Our current route lookups (mctp_route_lookup and mctp_route_lookup_null) traverse the net's route list without the RCU read lock held. This means the route lookup is subject to preemption, resulting in an potential grace period expiry, and so an eventual kfree() while we still have the route pointer. Add the proper read-side critical section locks around the route lookups, preventing pr... • https://git.kernel.org/stable/c/889b7da23abf92faf34491df95733bda63639e32 •

29 Feb 2024 — In the Linux kernel, the following vulnerability has been resolved: arm64: errata: Add Cortex-A520 speculative unprivileged load workaround Implement the workaround for ARM Cortex-A520 erratum 2966298. On an affected Cortex-A520 core, a speculatively executed unprivileged load might leak data from a privileged load via a cache side channel. The issue only exists for loads within a translation regime with the same translation (e.g. same ASID and VMID). Therefore, the issue only affects the return to EL0.
