CVE-2022-49975
CVE-2022-49975 affects the Linux kernel’s BPF path, where a redirect of packets with invalid pkt_len could occur. The root cause is described as a BPF program test/run path (bpf_prog_test_run_skb) redirecting empty skbs, leading to a potential flow handling issue in fq_codel_drop(). The vulnerabi...
CVE-2022-50082
CVE-2022-50082 affects the Linux kernel ext4 subsystem. The issue arises in ext4_iomap_begin due to a race between bmap and write, which can trigger a WARN_ON_ONCE path during file writes, evidenced by a kernel warning trace through iomap_apply → iomap_bmap → ext4_bmap → bmap. The consequence is ...
CVE-2022-50275
The CVE-2022-50275 issue affects the Linux kernel Radeon driver: the radeon_acpi_vfct_bios() path failed to call acpi_put_table() after ACPI BIOS parsing, causing an ACPI memory leak. The vulnerability is addressed by adding the missing acpi_put_table() call to release ACPI memory post-init, as d...
CVE-2022-50284
CVE-2022-50284 affects the Linux kernel (init_mqueue_fs). If setup_mq_sysctls() fails, the mqueue_inode_cachep was not released, causing a memory leak.

CVE-2022-50332
CVE-2022-50332 concerns a Linux kernel issue in video/aperture where sysfb_disable() must be called from aperture_remove_conflicting_pci_devices() before removing PCI devices to prevent simpledrm from binding to simple-framebuffer devices after the driver takes over. The vulnerability is describe...
CVE-2022-50388
CVE-2022-50388 affects the Linux kernel where a flush request initialized by blk_kick_flush can carry a NULL bio. With blktrace and multipath enabled, nvme_trace_bio_complete may dereference this NULL bio during io completion, leading to kernel NULL pointer dereference (crash) as shown by an OOPS...
CVE-2022-50422
CVE-2022-50422 affects the Linux kernel’s SCSI LIBSAS path. When SMP task execution fails, smp_execute_task_sg() calls del_timer() to remove slow_task->timer, but if sas_task_internal_timedout() is running, the timer isn’t stopped, causing a use-after-free of task->slow_task. The fix is to ...
CVE-2022-50430
CVE-2022-50430 affects the Linux kernel mmc vub300 driver. The fix prevents calling blocking operations when the current task is not TASK_RUNNING by ensuring vub300_enable_sdio_irq() uses proper mutex usage and marks the current task as TASK_RUNNING in a sleepable context. This reduces a potentia...
CVE-2022-50473
CVE-2022-50473 affects the Linux kernel cpufreq subsystem. The root cause is calling an uninitialized completion in cpufreq_sysfs_release() when kobject_init_and_add() fails, occurring in cpufreq_policy_alloc(). This can lead to a crash (page fault) on a local system via complete+0x98, with Call ...
CVE-2023-53169
CVE-2023-53169 concerns the Linux kernel resctrl path (x86/resctrl) where the rdt_domain’s staged_config[] was not cleared before/after use, allowing stale values to cause an MSR access error (WRMSR to 0xca0) when creating resource groups under CDP. The report describes resctrl_arch_update_domain...
CVE-2023-53172
CVE-2023-53172 concerns the Linux kernel fsverity feature. A change to FS_IOC_ENABLE_VERITY made it read data via __kernel_read() instead of direct pagecache, which made the WARN_ON_ONCE path reachable when the FD was opened with ioctl-only mode (mode 3). The fix is to reject FS_IOC_ENABLE_VERITY...
