CVE-2022-49293

The CVE-2022-49293 entry concerns the Linux kernel where the nf_tables code path in nft_do_chain had a bug in register initialization. The issue could allow a stack leak into userspace, with local attack vector and no user interaction required. The vulnerability is classified as LOCAL, with LOW a...

CVE-2022-49218 drm/dp: Fix OOB read when handling Post Cursor2 register

In the Linux kernel, the following vulnerability has been resolved: drm/dp: Fix OOB read when handling Post Cursor2 register The linkstatus array was not large enough to read the Adjust Request Post Cursor2 register, so remove the common helper function to avoid an OOB read, found with a...

CVE-2022-49218

CVE-2022-49218 is a Linux kernel vulnerability in the DRM DP driver: an OOB read when handling the Post Cursor2 register due to an undersized link_status array. The fix removes the common helper and replaces the fetch/decode path with an open-coded approach, mirroring the handling in a related DR...
