CVE-2022-50040

CVE-2022-50040 affects the Linux kernel internal DSA path for sja1105 (net: dsa: sja1105). The vulnerability is a buffer overflow caused when an error occurs in dsa_devlink_region_create(), leading to a negative index (-1) access of priv->regions. The issue has been fixed in the cited commits,...

CVE-2022-50036 drm/sun4i: dsi: Prevent underflow when computing packet sizes

In the Linux kernel, the following vulnerability has been resolved: drm/sun4i: dsi: Prevent underflow when computing packet sizes Currently, the packet overhead is subtracted using unsigned arithmetic. With a short sync pulse, this could underflow and wrap around to near the maximal u16 value. Fi...

CVE-2022-50035

CVE-2022-50035 affects the Linux kernel DRM AMDGPU path. The issue is a use-after-free in amdgpu_bo_list mutex handling caused by double-unlocking of bo_list_mutex when amdgpu_cs_vm_handling returns non-zero, which can lead to a refcount underflow (as shown in the trace). The vulnerability is dem...

CVE-2022-50028 gadgetfs: ep_io - wait until IRQ finishes

In the Linux kernel, the following vulnerability has been resolved: gadgetfs: epio - wait until IRQ finishes after usbepqueue if waitforcompletioninterruptible is interrupted we need to wait until IRQ gets finished. Otherwise complete from epiocomplete can corrupt stack...

CVE-2022-50028

CVE-2022-50028 affects gadgetfs ep_io in the Linux kernel (drivers/usb/gadget/legacy/inode.c). After usb_ep_queue(), if wait_for_completion_interruptible() is interrupted, code must wait for IRQ completion; otherwise epio_complete() may corrupt the stack. The vulnerability is fixed in the Linux k...

CVE-2022-50027

CVE-2022-50027 is a Linux kernel issue affecting the SCSI lpfc path, where a missing free for the iocbq on failure to issue the CMF WQE can cause a memory leak. The root cause is that if lpfc_sli4_issue_wqe fails (ret_val non-zero), the iocbq request structure is not consistently freed, leading t...

CVE-2022-50026

CVE-2022-50026 concerns a Linux kernel vulnerability where the NIC queue offset calculation could shift out of bounds during NIC queue validation. The root cause is related to how habanalabs/gaudi handling interacts with NIC queues, leading to potential out-of-bounds access. The CVSS metrics indi...
