| CVE-2022-50811 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: erofs: fix missing unmap if z_erofs_get_extent_compressedlen() fails Otherwise, meta buffers could be leaked. | ||||

| In the Linux kernel, the following vulnerability has been resolved: m68k: mm: Move initrd phys_to_virt handling after paging_init() When booting with an initial ramdisk on platforms where physical memory does not start at address zero (e.g. on Amiga): initrd: 0ef0602c - 0f800000 Zone ranges: DMA [mem 0x0000000008000000-0x000000f7ffffffff] Normal empty Movable zone start for each node Early memory node ranges node 0: [mem 0x0000000008000000-0x000000000f7fffff] Initmem setup node 0 [mem 0x0000000008000000-0x000000000f7fffff] Unable to handle kernel access at virtual address (ptrval) Oops: 00000000 Modules linked in: PC: [<00201d3c>] memcmp+0x28/0x56 As phys_to_virt() relies on m68k_memoffset and module_fixup(), it must not be called before paging_init(). Hence postpone the phys_to_virt handling for the initial ramdisk until after calling paging_init(). While at it, reduce #ifdef clutter by using IS_ENABLED() instead. | ||||

| CVE-2022-50875 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: of: overlay: fix null pointer dereferencing in find_dup_cset_node_entry() and find_dup_cset_prop() When kmalloc() fail to allocate memory in kasprintf(), fn_1 or fn_2 will be NULL, and strcmp() will cause null pointer dereference. | ||||

| In the Linux kernel, the following vulnerability has been resolved: media: s5p-mfc: Clear workbit to handle error condition During error on CLOSE_INSTANCE command, ctx_work_bits was not getting cleared. During consequent mfc execution NULL pointer dereferencing of this context led to kernel panic. This patch fixes this issue by making sure to clear ctx_work_bits always. | ||||

Reproduction script show as below, for analysis, see the comments: ``` #!/bin/bash cd /sys/kernel/tracing/ # 1. Register a 'disable_event' command, then: # 1) SOFT_DISABLED_BIT was set; # 2) trace_buffered_event_enable() was called first time; echo 'cmdline_proc_show:disable_event:initcall:initcall_finish' > \ set_ftrace_filter # 2. Enable the event registered, then: # 1) SOFT_DISABLED_BIT was cleared; # 2) trace_buffered_event_disable() was called first time; echo 1 > events/initcall/initcall_finish/enable # 3. Try to call into cmdline_proc_show(), then SOFT_DISABLED_BIT was # set again!!! cat /proc/cmdline # 4. Unregister the 'disable_event' command, then: # 1) SOFT_DISABLED_BIT was cleared again; # 2) trace_buffered_event_disable() was called second time!!! echo '!cmdline_proc_show:disable_event:initcall:initcall_finish' > \ set_ftrace_filter ``` To fix it, IIUC, we can change to call trace_buffered_event_enable() at fist time soft-mode enabled, and call trace_buffered_event_disable() at last time soft-mode disabled. | ||||

| CVE-2022-50855 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bpf: prevent leak of lsm program after failed attach In [0], we added the ability to bpf_prog_attach LSM programs to cgroups, but in our validation to make sure the prog is meant to be attached to BPF_LSM_CGROUP, we return too early if the check fails. This results in lack of decrementing prog's refcnt (through bpf_prog_put) leaving the LSM program alive past the point of the expected lifecycle. This fix allows for the decrement to take place.

| CVE-2022-50861 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: NFSD: Finish converting the NFSv2 GETACL result encoder The xdr_stream conversion inadvertently left some code that set the page_len of the send buffer. The XDR stream encoders should handle this automatically now. This oversight adds garbage past the end of the Reply message. Clients typically ignore the garbage, but NFSD does not need to send it, as it leaks stale memory contents onto the wire. | ||||
| CVE-2023-54195 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix timeout of a call that hasn't yet been granted a channel afs_make_call() calls rxrpc_kernel_begin_call() to begin a call (which may get stalled in the background waiting for a connection to become available); it then calls rxrpc_kernel_set_max_life() to set the timeouts - but that starts the call timer so the call timer might then expire before we get a connection assigned - leading to the following oops if the call stalled: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... CPU: 1 PID: 5111 Comm: krxrpcio/0 Not tainted 6.3.0-rc7-build3+ #701 RIP: 0010:rxrpc_alloc_txbuf+0xc0/0x157 ...

The timer will be started when the first packet is transmitted. It shouldn't be possible to trigger this directly from userspace through AF_RXRPC as sendmsg() will return EBUSY if the call is in the waiting-for-conn state if it dropped out of the wait due to a signal. | ||||
| CVE-2023-54197 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: Revert "Bluetooth: btsdio: fix use after free bug in btsdio_remove due to unfinished work" This reverts commit 1e9ac114c4428fdb7ff4635b45d4f46017e8916f. This patch introduces a possible null-ptr-def problem. Revert it.

| CVE-2022-50865 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: tcp: fix a signed-integer-overflow bug in tcp_add_backlog() The type of sk_rcvbuf and sk_sndbuf in struct sock is int, and in tcp_add_backlog(), the variable limit is caculated by adding sk_rcvbuf, sk_sndbuf and 64 * 1024, it may exceed the max value of int and overflow. This patch reduces the limit budget by halving the sndbuf to solve this issue since ACK packets are much smaller than the payload. | ||||
| CVE-2022-50866 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: ASoC: pxa: fix null-pointer dereference in filter() kasprintf() would return NULL pointer when kmalloc() fail to allocate. Need to check the return pointer before calling strcmp(). | ||||
| CVE-2023-54200 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: always release netdev hooks from notifier This reverts "netfilter: nf_tables: skip netdev events generated on netns removal". The problem is that when a veth device is released, the veth release callback will also queue the peer netns device for removal. Its possible that the peer netns is also slated for removal. In this case, the device memory is already released before the pre_exit hook of the peer netns runs: BUG: KASAN: slab-use-after-free in nf_hook_entry_head+0x1b8/0x1d0 Read of size 8 at addr ffff88812c0124f0 by task kworker/u8:1/45 Workqueue: netns cleanup_net Call Trace: nf_hook_entry_head+0x1b8/0x1d0 __nf_unregister_net_hook+0x76/0x510 nft_netdev_unregister_hooks+0xa0/0x220 __nft_release_hook+0x184/0x490 nf_tables_pre_exit_net+0x12f/0x1b0 .. Order is: 1. First netns is released, veth_dellink() queues peer netns device for removal 2. peer netns is queued for removal 3. peer netns device is released, unreg event is triggered 4. unreg event is ignored because netns is going down 5. pre_exit hook calls nft_netdev_unregister_hooks but device memory might be free'd already. | ||||
| CVE-2023-54201 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/efa: Fix wrong resources deallocation order When trying to destroy QP or CQ, we first decrease the refcount and potentially free memory regions allocated for the object and then request the device to destroy the object. If the device fails, the object isn't fully destroyed so the user/IB core can try to destroy the object again which will lead to underflow when trying to decrease an already zeroed refcount. Deallocate resources in reverse order of allocating them to safely free them. | ||||
| CVE-2022-50868 | 1 Linux | 1 Linux Kernel | 2025-12-31 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: hwrng: amd - Fix PCI device refcount leak for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() for the normal and error path. | ||||
