In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix missing lock on sync reset reload On sync reset reload work, when remote host updates devlink on reload actions performed on that host, it misses taking devlink lock before calling devlink_remote_reload_actions_performed() which results in triggering lock assert like the following: WARNING: CPU: 4 PID: 1164 at net/devlink/core.c:261 devl_assert_locked+0x3e/0x50 … CPU: 4 PID: 1164 Comm: kworker/u96:6 Tainted: G S W 6.10.0-rc2+ #116 Hardware name: Supermicro SYS-2028TP-DECTR/X10DRT-PT, BIOS 2.0 12/18/2015 Workqueue: mlx5_fw_reset_events mlx5_sync_reset_reload_work [mlx5_core] RIP: 0010:devl_assert_locked+0x3e/0x50 … Call Trace: <TASK> ? __warn+0xa4/0x210 ? devl_assert_locked+0x3e/0x50 ? report_bug+0x160/0x280 ? handle_bug+0x3f/0x80 ? • https://git.kernel.org/stable/c/84a433a40d0ebf3bbf36b8bfa58c6f45dc782344 https://git.kernel.org/stable/c/5d07d1d40aabfd61bab21115639bd4f641db6002 https://git.kernel.org/stable/c/98884e89c90d077f6fe6ba18e6cf6f914642f04e https://git.kernel.org/stable/c/091268f3c27a5b6d7858a3bb2a0dbcc9cd26ddb5 https://git.kernel.org/stable/c/572f9caa9e7295f8c8822e4122c7ae8f1c412ff9 •

https://notcve.org/view.php?id=CVE-2024-42265
In the Linux kernel, the following vulnerability has been resolved: protect the fetch of ->fd[fd] in do_dup2() from mispredictions both callers have verified that fd is not greater than ->max_fds; however, misprediction might end up with tofree = fdt->fd[fd]; being speculatively executed. That's wrong for the same reasons why it's wrong in close_fd()/file_close_fd_locked(); the same solution applies - array_index_nospec(fd, fdt->max_fds) could differ from fd only in case of speculative execution on mispredicted path. • https://git.kernel.org/stable/c/ed42e8ff509d2a61c6642d1825032072dab79f26 https://git.kernel.org/stable/c/41a6c31df77bd8e050136b0a200b537da9e1084a https://git.kernel.org/stable/c/08775b3d6ed117cf4518754ec7300ee42b6a5368 https://git.kernel.org/stable/c/3f480493550b6a23d3a65d095d6569d4a7f56a0f https://git.kernel.org/stable/c/5db999fff545b924b24c9afd368ef5c17279b176 https://git.kernel.org/stable/c/da72e783afd27d9f487836b2e6738146c0edd149 https://git.kernel.org/stable/c/1171ceccabfd596ca370c5d2cbb47d110c3f2fe1 https://git.kernel.org/stable/c/8aa37bde1a7b645816cda8b80df4753ec •

In the Linux kernel, the following vulnerability has been resolved: drm/i915/gem: Fix Virtual Memory mapping boundaries calculation Calculating the size of the mapped area as the lesser value between the requested size and the actual size does not consider the partial mapping offset. This can cause page fault access. Fix the calculation of the starting and ending addresses, the total size is now deduced from the difference between the end and start addresses. Additionally, the calculations have been rewritten in a clearer and more understandable form.
