| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-04-28 | CVE-2022-48641 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: fix memory leak when blob is malformed The bug fix was incomplete, it "replaced" crash with a memory leak. The old code had an assignment to "ret" embedded into the conditional, restore this. | 5.5 |
| 2024-04-28 | CVE-2022-48642 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_tables: fix percpu memory leak at nf_tables_addchain() It seems to me that percpu memory for chain stats started leaking since commit 3bc158f8d0330f0a ("netfilter: nf_tables: map basechain priority to hardware priority") when nft_chain_offload_priority() returned an error. | 5.5 |
| 2024-04-28 | CVE-2022-48647 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: sfc: fix TX channel offset when using legacy interrupts In legacy interrupt mode the tx_channel_offset was hardcoded to 1, but that's not correct if efx_sepparate_tx_channels is false. | 5.5 |
| 2024-04-28 | CVE-2022-48648 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: sfc: fix null pointer dereference in efx_hard_start_xmit Trying to get the channel from the tx_queue variable here is wrong because we can only be here if tx_queue is NULL, so we shouldn't dereference it. | 5.5 |
| 2024-04-28 | CVE-2022-48654 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: nfnetlink_osf: fix possible bogus match in nf_osf_find() nf_osf_find() incorrectly returns true on mismatch, this leads to copying uninitialized memory area in nft_osf which can be used to leak stale kernel stack data to userspace. | 5.5 |
| 2024-04-28 | CVE-2022-48656 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dmaengine: ti: k3-udma-private: Fix refcount leak bug in of_xudma_dev_get() We should call of_node_put() for the reference returned by of_parse_phandle() in fail path or when it is not used anymore. Here we only need to move the of_node_put() before the check. | 5.5 |
| 2024-04-28 | CVE-2022-48659 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mm/slub: fix to return errno if kmalloc() fails In create_unique_id(), kmalloc(, GFP_KERNEL) can fail due to out-of-memory, if it fails, return errno correctly rather than triggering panic via BUG_ON(); kernel BUG at mm/slub.c:5893!

| 2024-04-28 | CVE-2022-48660 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: gpiolib: cdev: Set lineevent_state::irq after IRQ register successfully When running gpio test on nxp-ls1028 platform with below command gpiomon --num-events=3 --rising-edge gpiochip1 25 There will be a warning trace as below: Call trace: free_irq+0x204/0x360 lineevent_free+0x64/0x70 gpio_ioctl+0x598/0x6a0 __arm64_sys_ioctl+0xb4/0x100 invoke_syscall+0x5c/0x130 ...... el0t_64_sync+0x1a0/0x1a4 The reason of this issue is that calling request_threaded_irq() function failed, and then lineevent_free() is invoked to release the resource. | 5.5 |
| 2024-04-28 | CVE-2022-48661 | Improper Resource Shutdown or Release vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: gpio: mockup: Fix potential resource leakage when register a chip If creation of software node fails, the locally allocated string array is left unfreed. | 5.5 |
| 2024-04-28 | CVE-2022-48663 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: gpio: mockup: fix NULL pointer dereference when removing debugfs We now remove the device's debugfs entries when unbinding the driver. This now causes a NULL-pointer dereference on module exit because the platform devices are unregistered *after* the global debugfs directory has been recursively removed. | 5.5 |
