For s2024.02.04 Bionic:linux-gcp-5.4 on instance n2d-standard-64 (suite ubuntu_qrt_kernel_security) test case KernelSecurityTest.test_360_stacksignal_memleak fails with "Kernel memory does not leak to userspace in signalstack (CVE-2009-2847)"
This particular test case has not failed on any previous cycles for Bionic:linux-gcp-5.4, but the failure is the same between run #1 and #2 of the test. A 3rd run is in progress, and if the results are any different I will link them here.
I have attached the full console output to this bug as well. |
