What is runc?

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore

The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.

What is YARA?

YARA 4.6.0 is the first minor in two years, and it is almost entirely bounds checks.

4.6.0 is YARA's first minor release since 4.5.0 in September 2024. It adds yr_get_version, nine more e_machine values in the elf module and a man-page sync; everything else is bug fixes across compiled-rule loading, the regex engine, the VM, ELF handling and Authenticode. Loading a compiled rule file now validates indices, external variables, arena buffers and Aho-Corasick states. The release credits Ada Logics and Anthropic among its contributors.

runc 1.6.0-rc.1 lifts the 1024-CPU limit and refuses settings it used to quietly ignore

◆ Current state

The 1.6.0 cycle opened on October 6 with a first release candidate that is mostly cleanup: deprecated libcontainer APIs removed, Go 1.26 now required, urfave/cli moved from v1 to v3, and the binary about 15% smaller on amd64. The changes with operational weight are that cpuAffinity and NUMA memoryPolicy no longer stop at 1024 CPUs or nodes, and that a container asking for a read-only rootfs without its own mount namespace is now refused. Eleven days earlier 1.5.2 worked around a kernel bug, present since v6.17, that corrupted memory inside runc and caused random crashes on cgroup v2. It also stopped runc exec --cgroup from escaping into a sibling cgroup.

◆ Where it's heading

The project keeps converting silent behaviour into explicit behaviour. Read-only requests that were ignored now fail, a umask that was dropped is now honoured, and poststart hooks moved to conform to the runtime spec. The same maintainers are shrinking the surface underneath, dropping the deprecated API and the high-level cilium/ebpf path, which took roughly 7.5% off the 1.5.2 binary. Stricter behaviour plus a smaller dependency set is what a component under every container host would be expected to do between majors.

◆ Prediction

1.5.0's notes pointed to a 1.6.0 in late October 2026, and the feed so far shows only rc.1, so further release candidates or the final are the next entries to expect. The refused read-only configurations are the change most likely to surface as user reports during testing.

YARA 4.6.0 is the first minor in two years, and it is almost entirely bounds checks.

◆ Current state

4.6.0 is YARA's first minor release since 4.5.0 in September 2024. It adds yr_get_version, nine more e_machine values in the elf module and a man-page sync; everything else is bug fixes across compiled-rule loading, the regex engine, the VM, ELF handling and Authenticode. Loading a compiled rule file now validates indices, external variables, arena buffers and Aho-Corasick states. The release credits Ada Logics and Anthropic among its contributors.

◆ Where it's heading

The parser-under-pressure reading holds, with wider scope. Earlier patches bounded single values; this release treats compiled rules and regex input as hostile throughout. Fixes for exponential growth on nested regex repeats and infinite loops show the review now covers resource exhaustion as well as corruption.

◆ Prediction

Expect 4.6.x patches in the same files, since this list is long and contributor-driven. Nothing here signals new language features; the three additions are small.
