Linux Distros Unpatched Vulnerability : CVE-2026-88816

high Nessus Plugin ID 350038

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- DBI versions before 1.654 for Perl incorrectly treat numeric values as strings in FetchHashKeyName.
fetchrow_hashref uses the string pointer of the FetchHashKeyName attribute as the key name without stringifying it first. When FetchHashKeyName has been set to an integer (IV) or floating-point (NV) value, that pointer is invalid, so reading the key name triggers a segmentation fault. This can be triggered with the following code: my $dbh = DBI->connect( dbi:ExampleP:, , , { RaiseError => 0, PrintError => 0 } ); $dbh->{FetchHashKeyName} = 42; my $sth = $dbh->prepare(select mode, size, name from .);
$sth->execute; $sth->fetchrow_hashref; (CVE-2026-88816)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
