In the Linux kernel, the following vulnerability has been resolved: crypto: caam - fix overflow on long hmac keys When a key longer than block size is supplied, it is copied and then hashed into the real key. The memory allocated for the copy needs to be rounded to DMA cache alignment, as otherwise the hashed key may corrupt neighbouring memory. The copying is performed using kmemdup, however this leads to an overflow: reading more bytes (aligned_len - keylen) from the keylen source buffer. Fix this by replacing kmemdup with kmalloc, followed by memcpy.

The remote Oracle Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2026-27288 advisory.

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - crypto: caam - fix overflow on long hmac keys When a key longer than block size is supplied, it is copied     and then hashed into the real key. The memory allocated for the copy needs to be rounded to DMA cache     alignment, as otherwise the hashed key may corrupt neighbouring memory. The copying is performed using     kmemdup, however this leads to an overflow: reading more bytes (aligned_len - keylen) from the keylen     source buffer. Fix this by replacing kmemdup with kmalloc, followed by memcpy. (CVE-2026-43330)

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