Vulnerability from github – Published: 2024-10-21 12:30 – Updated: 2025-11-04 00:31

Details

In the Linux kernel, the following vulnerability has been resolved:

block: fix potential invalid pointer dereference in blk_add_partition

The blk_add_partition() function initially used a single if-condition (IS_ERR(part)) to check for errors when adding a partition. This was modified to handle the specific case of -ENXIO separately, allowing the function to proceed without logging the error in this case. However, this change unintentionally left a path where md_autodetect_dev() could be called without confirming that part is a valid pointer.

This commit separates the error handling logic by splitting the initial if-condition, improving code readability and handling specific error scenarios explicitly. The function now distinguishes the general error case from -ENXIO without altering the existing behavior of md_autodetect_dev() calls.

Severity ?

5.5 (Medium)

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nblock: fix potential invalid pointer dereference in blk_add_partition\n\nThe blk_add_partition() function initially used a single if-condition\n(IS_ERR(part)) to check for errors when adding a partition. This was\nmodified to handle the specific case of -ENXIO separately, allowing the\nfunction to proceed without logging the error in this case. However,\nthis change unintentionally left a path where md_autodetect_dev()\ncould be called without confirming that part is a valid pointer.\n\nThis commit separates the error handling logic by splitting the\ninitial if-condition, improving code readability and handling specific\nerror scenarios explicitly. The function now distinguishes the general\nerror case from -ENXIO without altering the existing behavior of\nmd_autodetect_dev() calls."
