CVE-2022-49577
Status: ModifiedMedium (4.7)—
In the Linux kernel, the following vulnerability has been resolved:
udp: Fix a data-race around sysctl_udp_l3mdev_accept.
While reading sysctl_udp_l3mdev_accept, it can be changed concurrently. Thus, we need to add READ_ONCE() to its reader.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H
- Base score: 4.7
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.18%
- Percentile among all scored CVEs: 7
- Score date: 10/6/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
