In the Linux kernel, the following vulnerability has been resolved: srcu: Tighten cleanup_srcu_struct() GP checks Currently, cleanup_srcu_struct() checks for a grace period in progress, but it does not check for a grace period that has not yet started but which might start at any time. Such a situation could result in a use-after-free bug, so this commit adds a check for a grace period that is needed but not yet started to cleanup_srcu_struct().

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

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

An update of the linux package has been released.

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

  - In the Linux kernel, the following vulnerability has been resolved: srcu: Tighten cleanup_srcu_struct() GP     checks Currently, cleanup_srcu_struct() checks for a grace period in progress, but it does not check for a     grace period that has not yet started but which might start at any time. Such a situation could result in     a use-after-free bug, so this commit adds a check for a grace period that is needed but not yet started to     cleanup_srcu_struct(). (CVE-2022-49651)

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