Summary

In the Linux kernel, the following vulnerability has been resolved: partitions: mac: fix handling of bogus partition table Fix several issues in partition probing: - The bailout for a bad partoffset must use put_dev_sector(), since the preceding read_part_sector() succeeded. - If the partition table claims a silly sector size like 0xfff bytes (which results in partition table entries straddling sector boundaries), bail out instead of accessing out-of-bounds memory. - We must not assume that the partition table contains proper NUL termination - use strnlen() and strncmp() instead of strlen() and strcmp().

Physical media insertion is one route, but the loop-device path makes plain local access sufficient, which is the broader and more severe vector.\nAC:L - The attacker fully controls `block_size` and every partition-entry offset in the image, so the straddling out-of-bounds access is deterministic on every probe \u2014 no race, no unknown memory state, no retry needed. CONFIG_MAC_PARTITION is enabled by default in mainstream distro kernels, so no rare configuration is required.\nPR:L - `loop_configure()`/`LOOP_SET_FD` with LO_FLAGS_PARTSCAN performs no capability check \u2014 an unprivileged user holding an open fd on a loop device can bind an arbitrary crafted image file and force the scan. Container, appliance, and sandbox deployments routinely expose loop or removable block devices to non-root users.\nUI:N - The attacker supplies and attaches the malicious image itself and triggers the partition rescan directly; no victim needs to mount, open, or otherwise interact with anything. Hotplug scanning likewise runs automatically at add_disk() with no user action.\nS:U - The out-of-bounds read and write stay within the kernel\u0027s own address space and are handled by the same security authority that owns the block layer. No VM, IOMMU, or sandbox boundary is crossed.\nC:H - Up to 135 bytes of kernel memory past the end of a page-cache folio are read, and those bytes are propagated into partition start/size values that are exposed world-readable through /proc/partitions and sysfs, giving a repeatable kernel-heap disclosure primitive. The read is not narrowly bounded and the attacker chooses the exact offset past the page via secsize and slot.\nI:H - On CONFIG_PPC_PMAC (where MAC_PARTITION is default-y) mac_fix_string() writes NUL bytes into memory beyond the folio at an attacker-chosen offset, an out-of-bounds write into adjacent kernel heap. Kernel partition state is additionally constructed from out-of-bounds memory contents.\nA:H - Reading and writing past the end of a page-cache folio can fault or corrupt adjacent kernel structures, producing an oops or panic (and an immediate KASAN-detected fault on hardened kernels). The missing put_dev_sector() also leaks a folio reference on every bogus-partoffset probe, permanently pinning page-cache pages under repeated triggering."
