CVE-2019-19076
Published: 18 November 2019
** DISPUTED ** A memory leak in the nfp_abm_u32_knode_replace() function in drivers/net/ethernet/netronome/nfp/abm/cls.c in the Linux kernel before 5.3.6 allows attackers to cause a denial of service (memory consumption), aka CID-78beef629fd9. NOTE: This has been argued as not a valid vulnerability. The upstream commit 78beef629fd9 was reverted.
From the Ubuntu Security Team
It was discovered that there was a memory leak in the Advanced Buffer Management functionality of the Netronome NFP4000/NFP6000 NIC Driver in the Linux kernel during certain error scenarios. A local attacker could use this to cause a denial of service (memory exhaustion).
Notes
| Author | Note |
|---|---|
| sbeattie | reverted in 1d1997db870f4058676439ef7014390ba9e24eb2, in part due to upstream determining that there was no memory leak. |
