| 2024-03-26 | CVE-2023-52625 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Refactor DMCUB enter/exit idle interface [Why] We can hang in place trying to send commands when the DMCUB isn't powered on. [How] We need to exit out of the idle state prior to sending a command, but the process that performs the exit also invokes a command itself. Fixing this issue involves the following: 1. | 5.5 |
| 2024-03-26 | CVE-2024-26646 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: thermal: intel: hfi: Add syscore callbacks for system-wide PM The kernel allocates a memory buffer and provides its location to the hardware, which uses it to update the HFI table. | 5.5 |
| 2024-03-26 | CVE-2024-26647 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix late derefrence 'dsc' check in 'link_set_dsc_pps_packet()' In link_set_dsc_pps_packet(), 'struct display_stream_compressor *dsc' was dereferenced in a DC_LOGGER_INIT(dsc->ctx->logger); before the 'dsc' NULL pointer check. Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/link/link_dpms.c:905 link_set_dsc_pps_packet() warn: variable dereferenced before check 'dsc' (see line 903) | 5.5 |

| 2024-03-25 | CVE-2021-47159 | Infinite Loop vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: dsa: fix a crash if ->get_sset_count() fails If ds->ops->get_sset_count() fails then it "count" is a negative error code such as -EOPNOTSUPP. | 5.5 |
| 2024-03-25 | CVE-2021-47162 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tipc: skb_linearize the head skb when reassembling msgs It's not a good idea to append the frag skb to a skb's frag_list if the frag_list already has skbs from elsewhere, such as this skb was created by pskb_copy() where the frag_list was cloned (all the skbs in it were skb_get'ed) and shared by multiple skbs. However, the new appended frag skb should have been only seen by the current skb. | 5.5 |
| 2024-03-25 | CVE-2021-47163 | Improper Locking vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tipc: wait and exit until all work queues are done On some host, a crash could be triggered simply by repeating these commands several times: # modprobe tipc # tipc bearer enable media udp name UDP1 localip 127.0.0.1 # rmmod tipc [] BUG: unable to handle kernel paging request at ffffffffc096bb00 [] Workqueue: events 0xffffffffc096bb00 [] Call Trace: [] ? process_one_work+0x1a7/0x360 [] ? worker_thread+0x30/0x390 [] ? create_worker+0x1a0/0x1a0 [] ? kthread+0x116/0x130 [] ? kthread_flush_work_fn+0x10/0x10 [] ? ret_from_fork+0x35/0x40 When removing the TIPC module, the UDP tunnel sock will be delayed to release in a work queue as sock_release() can't be done in rtnl_lock(). If the work queue is schedule to run after the TIPC module is removed, kernel will crash as the work queue function cleanup_beareri() code no longer exists when trying to invoke it. To fix it, this patch introduce a member wq_count in tipc_net to track the numbers of work queues in schedule, and wait and exit until all work queues are done in tipc_exit_net(). | 5.5 |
| 2024-03-25 | CVE-2021-47166 | Out-of-bounds Write vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: NFS: Don't corrupt the value of pg_bytes_written in nfs_do_recoalesce() The value of mirror->pg_bytes_written should only be updated after a successful attempt to flush out the requests on the list. | 5.5 |
| 2024-03-25 | CVE-2021-47167 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: NFS: Fix an Oopsable condition in __nfs_pageio_add_request() Ensure that nfs_pageio_error_cleanup() resets the mirror array contents, so that the structure reflects the fact that it is now empty. Also change the test in nfs_pageio_do_add_request() to be more robust by checking whether or not the list is empty rather than relying on the value of pg_count. | 5.5 |
| 2024-03-25 | CVE-2021-47168 | Out-of-bounds Write vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: NFS: fix an incorrect limit in filelayout_decode_layout() The "sizeof(struct nfs_fh)" is two bytes too large and could lead to memory corruption. | 5.5 |
