CVE-2024-25739: n/a
CVE-2024-25739 is a medium severity vulnerability in the Linux kernel up to version 6. 7. 4. It involves the create_empty_lvol function in the drivers/mtd/ubi/vtbl. c file, which can attempt to allocate zero bytes due to a missing check on ubi->leb_size, leading to a crash. This vulnerability does not impact confidentiality or integrity but causes a denial of service by crashing the kernel. No known exploits are reported in the wild. There is no explicit patch or remediation information currently available.
AI Analysis
Technical Summary
The vulnerability CVE-2024-25739 exists in the Linux kernel through version 6.7.4 within the create_empty_lvol function located in drivers/mtd/ubi/vtbl.c. The issue arises because the function can attempt to allocate zero bytes due to a missing validation check on the ubi->leb_size variable. This improper handling can cause the kernel to crash, resulting in a denial of service condition. The CVSS 3.1 base score is 5.5, reflecting a medium severity with local attack vector, low complexity, requiring low privileges, no user interaction, and impacting availability only. No patch or official remediation guidance is currently documented.
Potential Impact
The vulnerability causes a denial of service by crashing the Linux kernel when create_empty_lvol attempts to allocate zero bytes. It does not affect confidentiality or integrity. The crash can disrupt system availability, potentially requiring a reboot or manual intervention to restore normal operation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should monitor vendor channels for updates. No specific mitigations are documented at this time.
