Page history
Changes are dated when recorded; day views use the last saved version from that UTC day, and citations stay fixed.
CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.
Which CVEs have scores here?
This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.
No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Published
RDMA/umem: Be careful about boundary conditions in ib_umem_find_best_pgsz()
In the Linux kernel, the following vulnerability has been resolved:
RDMA/umem: Be careful about boundary conditions in ib_umem_find_best_pgsz()
Several corner cases, especially important on 32 bits:
- umem->iova is u64, the function argument should pass in u64 or
iova will be truncated
- Check that the length is not too large for the iova
- Check that lengths > 4G don't overflow the GENMASK
