Page history
Changes are dated when recorded; day views use the last saved version from that UTC day, and citations stay fixed.
CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

smb: client: fix one-byte OOB read in smb2_parse_native_symlink()
In the Linux kernel, the following vulnerability has been resolved:
smb: client: fix one-byte OOB read in smb2_parse_native_symlink()
When parsing a share-root relative native symlink, memcpy copies
smb_target+1 (skipping the leading separator) but uses
strlen(smb_target)+1 as the length, reading one byte past the
allocated buffer.
This fixes the following KASAN splat when accessing an SMB symlink
with a target of '\a\b':
