CVE-2023-53097: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: powerpc/iommu: fix memory leak with using debugfs_lookup() When calling debugfs_lookup() the result must have dput() called on it, otherwise the memory will leak over time. To make things simpler, just call debugfs_lookup_and_remove() instead which handles all of the logic at once.

Affected products

• Linux Linux Kernel: before 5.15.103 (fixed in 5.15.103); from 5.16, before 6.1.20 (fixed in 6.1.20); from 6.2, before 6.2.7 (fixed in 6.2.7)
