Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2022-49083 - Priority: Routine - CVSS: 5.5 (medium) - EPSS: 0.0025 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Feb 26, 2025 ## Description In the Linux kernel, the following vulnerability has been resolved: iommu/omap: Fix regression in probe for NULL pointer dereference Commit 3f6634d997db ("iommu: Use right way to retrieve iommu_ops") started triggering a NULL pointer dereference for some omap variants: __iommu_probe_device from probe_iommu_group+0x2c/0x38 probe_iommu_group from bus_for_each_dev+0x74/0xbc bus_for_each_dev from bus_iommu_probe+0x34/0x2e8 bus_iommu_probe from bus_set_iommu+0x80/0xc8 bus_set_iommu from omap_iommu_init+0x88/0xcc omap_iommu_init from do_one_initcall+0x44/0x24 This is caused by omap iommu probe returning 0 instead of ERR_PTR(-ENODEV) as noted by Jason Gunthorpe . Looks like the regression already happened with an earlier commit 6785eb9105e3 ("iommu/omap: Convert to probe/release_device() call-backs") that changed the function return type and missed converting one place. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | linux Debian 12.15 (bookworm) | 5.17.3-1 | [DEBIAN-CVE-2022-49083](https://patchblox.com/security/data/fix/linux/debian-cve-2022-49083.md) | Feb 26, 2025 | | Linux | linux Debian 13.5 (trixie) | 5.17.3-1 | [DEBIAN-CVE-2022-49083](https://patchblox.com/security/data/fix/linux/debian-cve-2022-49083.md) | Feb 26, 2025 | | Linux | linux Debian 14 | 5.17.3-1 | [DEBIAN-CVE-2022-49083](https://patchblox.com/security/data/fix/linux/debian-cve-2022-49083.md) | Feb 26, 2025 | --- Data as of 2026-11-08T06:59:42Z UTC.
