CVE-2026-80670

CVE-2026-80670 affects the Linux kernel perf tools subsystem. The function machine__resolve() accesses env->cpu[al->cpu].socket_id after validating al->cpu >= 0 and env->cpu != NULL, but fails to validate al->cpu against env->nr_cpus_avail. Because al->cpu originates from ...

SUSE CVE-2026-72066

In the Linux kernel, the following vulnerability has been resolved: cpu: hotplug: Bound hotplug states sysfs output statesshow adds CPU hotplug state names into a single sysfs buffer using sprintf. With enough registered states, this can write past the end of the PAGESIZE buffer. Use sysfsemitat ...

SUSE CVE-2026-72067

In the Linux kernel, the following vulnerability has been resolved: cpu: hotplug: Preserve per instance callback errors cpuhpinvokecallback unwinds earlier callbacks for the same hotplug state when one instance fails. The rollback path currently reuses ret, so a successful rollback can hide the...

CVE-2026-40019

An unauthenticated attacker can send a truncated quoted argument to the ManageSieve login process, which makes it spin in an infinite loop consuming CPU. This can cause degradation or denial of service for Sieve script management, and repeated connections can consume all available CPU on the...

CVE-2026-40019: Uncontrolled Resource Consumption

An unauthenticated attacker can send a truncated quoted argument to the ManageSieve login process, which makes it spin in an infinite loop consuming CPU. This can cause degradation or denial of service for Sieve script management, and repeated connections can consume all available CPU on the...

UBUNTU-CVE-2026-40014

An attacker that can send mail to a user can craft a message header that makes the IMAP THREAD command consume CPU disproportionate to the size of the message. When a mail client issues a THREAD command on the affected mailbox, this can cause degradation or denial of service for IMAP. Monitor...

UBUNTU-CVE-2026-52681

Sieve CPU resource usage is tracked in the compiled script, so an attacker that has valid credentials can reset the accounting by repeatedly changing the active script. Compiled script files are also not removed when a script is deleted or renamed. The configured Sieve CPU limit can be bypassed,...

CVE-2026-40014: Uncontrolled Resource Consumption

CVE-2026-40017: Uncontrolled Resource Consumption

An attacker that can send mail to a user can craft a message header whose values are chosen to collide in an internal hash table, which makes the IMAP THREAD command consume CPU disproportionate to the size of the message. This is a separate issue from CVE-2026-40014 and is not addressed by that...

CVE-2026-52681: Excessive Platform Resource Consumption within a Loop
