| 2025-01-08 | CVE-2024-56785 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: MIPS: Loongson64: DTS: Really fix PCIe port nodes for ls7a Fix the dtc warnings: arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider arch/mips/boot/dts/loongson/ls7a-pch.dtsi:68.16-416.5: Warning (interrupt_provider): /bus@10000000/pci@1a000000: '#interrupt-cells' found, but node is not an interrupt provider arch/mips/boot/dts/loongson/loongson64g_4core_ls7a.dtb: Warning (interrupt_map): Failed prerequisite 'interrupt_provider' And a runtime warning introduced in commit 045b14ca5c36 ("of: WARN on deprecated #address-cells/#size-cells handling"): WARNING: CPU: 0 PID: 1 at drivers/of/base.c:106 of_bus_n_addr_cells+0x9c/0xe0 Missing '#address-cells' in /bus@10000000/pci@1a000000/pci_bridge@9,0 The fix is similar to commit d89a415ff8d5 ("MIPS: Loongson64: DTS: Fix PCIe port nodes for ls7a"), which has fixed the issue for ls2k (despite its subject mentions ls7a). | 5.5 |
| 2025-01-08 | CVE-2024-56786 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: bpf: put bpf_link's program when link is safe to be deallocated In general, BPF link's underlying BPF program should be considered to be reachable through attach hook -> link -> prog chain, and, pessimistically, we have to assume that as long as link's memory is not safe to free, attach hook's code might hold a pointer to BPF program and use it. As such, it's not (generally) correct to put link's program early before waiting for RCU GPs to go through. | 5.5 |
| 2025-01-08 | CVE-2024-56787 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: soc: imx8m: Probe the SoC driver as platform driver With driver_async_probe=* on kernel command line, the following trace is produced because on i.MX8M Plus hardware because the soc-imx8m.c driver calls of_clk_get_by_name() which returns -EPROBE_DEFER because the clock driver is not yet probed. | 5.5 |
| 2025-01-06 | CVE-2024-56757 | Improper Resource Shutdown or Release vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btusb: mediatek: add intf release flow when usb disconnect MediaTek claim an special usb intr interface for ISO data transmission. The interface need to be released before unregistering hci device when usb disconnect. | 5.5 |
| 2025-01-06 | CVE-2024-56759 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: btrfs: fix use-after-free when COWing tree bock and tracing is enabled When a COWing a tree block, at btrfs_cow_block(), and we have the tracepoint trace_btrfs_cow_block() enabled and preemption is also enabled (CONFIG_PREEMPT=y), we can trigger a use-after-free in the COWed extent buffer while inside the tracepoint code. | 7.8 |
| 2025-01-06 | CVE-2024-56763 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tracing: Prevent bad count for tracing_cpumask_write If a large count is provided, it will trigger a warning in bitmap_parse_user. Also check zero for it. | 5.5 |
| 2025-01-06 | CVE-2024-56769 | Use of Uninitialized Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: dvb-frontends: dib3000mb: fix uninit-value in dib3000_write_reg Syzbot reports [1] an uninitialized value issue found by KMSAN in dib3000_read_reg(). Local u8 rb[2] is used in i2c_transfer() as a read buffer; in case that call fails, the buffer may end up with some undefined values. Since no elaborate error handling is expected in dib3000_write_reg(), simply zero out rb buffer to mitigate the problem.

| 2025-01-02 | CVE-2022-49035 | Allocation of Resources Without Limits or Throttling vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: media: s5p_cec: limit msg.len to CEC_MAX_MSG_SIZE I expect that the hardware will have limited this to 16, but just in case it hasn't, check for this corner case. | 5.5 |
| 2024-12-29 | CVE-2024-56746 | Memory Leak vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: fbdev: sh7760fb: Fix a possible memory leak in sh7760fb_alloc_mem() When information such as info->screen_base is not ready, calling sh7760fb_free_mem() does not release memory correctly. | 5.5 |
| 2024-12-28 | CVE-2024-56692 | Improper Check for Unusual or Exceptional Conditions vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to do sanity check on node blkaddr in truncate_node() syzbot reports a f2fs bug as below: ------------[ cut here ]------------ kernel BUG at fs/f2fs/segment.c:2534!
