| 2024-08-21 | CVE-2022-48867 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: dmaengine: idxd: Prevent use after free on completion memory On driver unload any pending descriptors are flushed at the time the interrupt is freed: idxd_dmaengine_drv_remove() -> drv_disable_wq() -> idxd_wq_free_irq() -> idxd_flush_pending_descs(). If there are any descriptors present that need to be flushed this flow triggers a "not present" page fault as below: BUG: unable to handle page fault for address: ff391c97c70c9040 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page The address that triggers the fault is the address of the descriptor that was freed moments earlier via: drv_disable_wq()->idxd_wq_free_resources() Fix the use after free by freeing the descriptors after any possible usage. | 7.8 |
| 2024-08-21 | CVE-2022-48871 | Out-of-bounds Read vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: tty: serial: qcom-geni-serial: fix slab-out-of-bounds on RX FIFO buffer Driver's probe allocates memory for RX FIFO (port->rx_fifo) based on default RX FIFO depth, e.g. | 7.1 |
| 2024-08-21 | CVE-2022-48872 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Fix use-after-free race condition for maps It is possible that in between calling fastrpc_map_get() until map->fl->lock is taken in fastrpc_free_map(), another thread can call fastrpc_map_lookup() and get a reference to a map that is about to be deleted. Rewrite fastrpc_map_get() to only increase the reference count of a map if it's non-zero. | 7.0 |
| 2024-08-21 | CVE-2022-48873 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Don't remove map on creater_process and device_release Do not remove the map from the list on error path in fastrpc_init_create_process, instead call fastrpc_map_put, to avoid use-after-free. | 7.8 |
| 2024-08-21 | CVE-2022-48874 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: misc: fastrpc: Fix use-after-free and race in fastrpc_map_find Currently, there is a race window between the point when the mutex is unlocked in fastrpc_map_lookup and the reference count increasing (fastrpc_map_get) in fastrpc_map_find, which can also lead to use-after-free. So lets merge fastrpc_map_find into fastrpc_map_lookup which allows us to both protect the maps list by also taking the &fl->lock spinlock and the reference count, since the spinlock will be released only after. Add take_ref argument to make this suitable for all callers. | 7.8 |
| 2024-08-21 | CVE-2022-48878 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_qca: Fix driver shutdown on closed serdev The driver shutdown callback (which sends EDL_SOC_RESET to the device over serdev) should not be invoked when HCI device is not open (e.g. | 7.8 |
| 2024-08-21 | CVE-2022-48881 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: platform/x86/amd: Fix refcount leak in amd_pmc_probe pci_get_domain_bus_and_slot() takes reference, the caller should release the reference by calling pci_dev_put() after use. | 7.1 |
| 2024-08-21 | CVE-2022-48892 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: sched/core: Fix use-after-free bug in dup_user_cpus_ptr() Since commit 07ec77a1d4e8 ("sched: Allow task CPU affinity to be restricted on asymmetric systems"), the setting and clearing of user_cpus_ptr are done under pi_lock for arm64 architecture. | 7.8 |
| 2024-08-21 | CVE-2023-52906 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net/sched: act_mpls: Fix warning during failed attribute validation The 'TCA_MPLS_LABEL' attribute is of 'NLA_U32' type, but has a validation type of 'NLA_VALIDATE_FUNCTION'. | 7.8 |
| 2024-08-21 | CVE-2024-43873 | Missing Initialization of Resource vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: vhost/vsock: always initialize seqpacket_allow There are two issues around seqpacket_allow: 1. | 7.8 |
