Published : Oct. 24, 2025, 1:15 p.m. | 1\u00a0hour, 27\u00a0minutes ago<\/p>\n
Description : In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/xe\/vf: Don’t expose sysfs attributes not applicable for VFs<\/p>\n
VFs can’t read BMG_PCIE_CAP(0x138340) register nor access PCODE
\n(already guarded by the info.skip_pcode flag) so we shouldn’t
\nexpose attributes that require any of them to avoid errors like:<\/p>\n
[] xe 0000:03:00.1: [drm] Tile0: GT0: VF is trying to read an
\n inaccessible register 0x138340+0x0
\n [] RIP: 0010:xe_gt_sriov_vf_read32+0x6c2\/0x9a0 [xe]\n [] Call Trace:
\n [] xe_mmio_read32+0x110\/0x280 [xe]\n [] auto_link_downgrade_capable_show+0x2e\/0x70 [xe]\n [] dev_attr_show+0x1a\/0x70
\n [] sysfs_kf_seq_show+0xaa\/0x120
\n [] kernfs_seq_show+0x41\/0x60<\/p>\n
(cherry picked from commit a2d6223d224f333f705ed8495bf8bebfbc585c35)<\/p>\n
