AlmaLinux 9.2 [TuxCare] Security Update: bpftool / kernel / kernel-abi-stablelists / kernel-core / etc Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2026:1787935638)

"The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1787935638 advisory. - In the Linux kernel, the following vulnerability has been resolved: fs/mountsetattr: always cleanup mountkattr Make sure that...

SUSE CVE-2026-97921

In the Linux kernel, the following vulnerability has been resolved: tracing: Free histogram the field rejected for a bad modifier Writing a hist trigger whose value or variable carries a modifier that is not allowed there leaks the fields that were built for it. createvalfield takes the field fro...

SUSE CVE-2026-97936

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix memory corruption from the histogram stacktrace modifier parsefield sets HISTFIELDFLSTACKTRACE from the ".stacktrace" modifier before it looks the field name up, and nothing afterwards checks that the name resolved t...

CVE-2026-97922

A flaw was found in the Linux kernel's tracing subsystem. This vulnerability allows a privileged local user to cause a Denial of Service DoS through memory exhaustion. By repeatedly creating and removing histogram event triggers that reference the same variable multiple times, the kernel fails to...

CVE-2026-97921

A flaw was found in the Linux kernel's tracing subsystem. When configuring event histogram triggers, specifying an unpermitted modifier for a value or variable fails to release previously allocated memory on error. A local user with tracing access can exploit this flaw by repeatedly submitting...

CVE-2026-97920

A flaw was found in the Linux kernel. A local user could trigger this vulnerability by reading an event tracing histogram file when a memory allocation failure occurs. Because an error code overwrites the entry counter during cleanup, the system treats the error as an extremely large positive...

CVE-2026-97919

A flaw was found in the Linux kernel's tracing subsystem. When creating a named histogram trigger, the kernel registers the trigger before completing its setup. If initialization fails, the object is freed without being removed from the global tracking list. A local attacker can exploit this flaw...

DEBIAN-CVE-2026-97920

In the Linux kernel, the following vulnerability has been resolved: tracing: Keep the entry count when the histogram stats allocation fails printentries uses nentries both as the number of sort entries and as its own return value, so the -ENOMEM it stores when the stats allocation fails overwrite...
