In the Linux kernel, the following vulnerability has been resolved: drm/drv: Fix potential memory leak in drm_dev_init() drm_dev_init() will add drm_dev_init_release() as a callback. When drmm_add_action() failed, the release function won't be added. As the result, the ref cnt added by device_get() in drm_dev_init() won't be put by drm_dev_init_release(), which leads to the memleak. Use drmm_add_action_or_reset() instead of drmm_add_action() to prevent memleak. unreferenced object 0xffff88810bc0c800 (size 2048): comm "modprobe", pid 8322, jiffies 4305809845 (age 15.292s) hex dump (first 32 byt

Grounded briefings

Catalog interpretations for three audiences. Each brief cites ingested metadata and the original advisories below. They are not independent research and they do not invent exploit steps.

Executive

CVE-2022-49830 is a none public vulnerability record for Linux Linux. It is not currently listed in the CISA Known Exploited catalog. Check the linked vendor or CERT advisories for patch status. This summary is a catalog interpretation of the ingested metadata and cites the original advisories below.

System administrator

Identify whether Linux Linux is in your estate, then compare installed versions with the affected ranges. Affected packages or ranges on record: Linux Linux 2cbf7fc6718b9443ecd6261308c6348d8ffcccae <07e56de8766fe5be67252596244b84ac0ec0de91 (2cbf7fc6718b9443ecd6261308c6348d8ffcccae <07e56de8766fe5be67252596244b84ac0ec0de91). Check the linked vendor or CERT advisories for patch status. Prefer the vendor or distribution advisory linked in Sources before changing production systems. This is a catalog interpretation, not a runbook.
