CVE-2026-72011

A flaw was found in the Linux kernel's s390/diag component. A local user could exploit a missing bounds check when handling a user-controlled 'level' variable, which is used to read from an array. This vulnerability could lead to information disclosure through speculative execution, potentially...

CVE-2026-72011

The CVE-2026-72011 issue concerns the Linux kernel on s390 where a read from an array used by a user-space controlled level could be exploited via speculative execution. The fix adds a missing array_index_nospec() call to memtop_get_page_count() to mitigate speculative access. Connected documents...

UBUNTU-CVE-2023-53205

In the Linux kernel, the following vulnerability has been resolved: KVM: s390/diag: fix racy access of physical cpu number in diag 9c handler We do check for target CPU == -1, but this might change at the time we are going to use it. Hold the physical target CPU in a local variable to avoid...

CVE-2023-53205

CVE-2023-53205 affects the Linux kernel KVM on s390, specifically the diag 9c handler where a race exists around the target CPU value (-1). The fix stores the physical target CPU in a local variable to prevent out-of-bounds accesses to CPU arrays. The CVE’s risk is described as high (CVSS v3.1: A...
