Container Storage Modules: Use of Insufficiently Random Values
CVE-2026-76105 is a high-severity use of insufficiently random values vulnerability in Container Storage Modules from Dell, with a CVSS 3.1 base score of 7.1 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 1.18.0 or later as the first without the flaw, so updating Container Storage Modules to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.1% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Container Storage Modules to 1.18.0 or later or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.

Official description
Dell Container Storage Modules, versions prior to 1.18.0 contain(s) an Use of Insufficiently Random Values vulnerability. An unauthenticated attacker with local access could potentially exploit this vulnerability, leading to Information tampering.

The underlying weakness: Use of Insufficiently Random Values
The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.
How developers prevent this class of flaw
- Use a well-vetted algorithm that is currently considered to be strong by experts in the field, and select well-tested implementations with adequate length seeds. In general, if a pseudo-random number generator is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts. Pseudo-random number generators can produce predictable numbers if the generator is known and the seed can be guessed. A 256-bit seed is a good starting point for producing a random enough number.
- Consider a PRNG that re-seeds itself as needed from high quality pseudo-random output sources, such as hardware devices.
- Use products or modules that conform to FIPS 140-2 to avoid obvious entropy problems. Consult FIPS 140-2 Annex C (Approved Random Number Generators).
