CVE-2026-47770

jq is a command-line JSON processor. Prior to 1.8.2, comparing two sufficiently deeply nested arrays with the == operator exhausts the C stack on jq's ordinary command-line surface, resulting in denial of service via stack exhaustion uncontrolled recursion. The crash occurs in jq's recursive...

CVE-2026-47770 jq: stack overflow in deep structural equality

jq is a command-line JSON processor. Prior to 1.8.2, comparing two sufficiently deeply nested arrays with the == operator exhausts the C stack on jq's ordinary command-line surface, resulting in denial of service via stack exhaustion uncontrolled recursion. The crash occurs in jq's recursive...

jq: jq: Denial of Service via deeply nested array comparison

A flaw was found in jq, a command-line JSON processor. This vulnerability allows a local user or an attacker providing malicious input to cause a denial of service DoS by comparing two sufficiently deeply nested arrays using the '==' operator. This action exhausts the C stack due to uncontrolled...

jq: signed-int overflow in stack_reallocate

A flaw was found in jq, a command line JSON processor. The memory allocation size is calculated using a signed integer that can overflow when processing deeply nested generator forks. This integer overflow allows an attacker who can supply a sufficiently nested input to influence the memory...

jq: stack overflow in recursive object merge

A flaw was found in jq, a command line JSON processor. The jvobjectmergerecursive function, reachable via the operator when both operands are objects, does not have a depth limit when processing nested objects. This missing depth limit allows an attacker who can supply a sufficiently nested input...

jq: stack overflow via unbounded recursion in jv_contains

A flaw was found in jq, a command line JSON processor. The jvcontains function does not have a depth limit when processing nested arrays or objects. This missing depth limit allows an attacker who can supply a sufficiently nested input structure to exhaust the stack memory, causing an application...

CVE-2026-53261

In the Linux kernel, the following vulnerability has been resolved: devlink: Release nested relation on devlink free devlink relation state is normally released from devlunregister, which calls devlinkrelput. This misses devlink instances that get a nested relation before registration and then fa...

CVE-2026-53260

In the Linux kernel, the following vulnerability has been resolved: tcp: Add preemptdisable,enablenested in reqskqueuehashreq. syzbot reported a weird reqsk-rskrefcnt underflow in inetcskreqskqueuedrop. The captured reqskput in inetcskreqskqueuedrop is called only when it successfully removes req...

CVE-2026-53182

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: reject oversized EMA RNR lists nl80211parsernrelems stores the parsed element count in a u8-backed cfg80211rnrelems::cnt field and uses that count to size the flexible array allocation. Reject nested...

Security Bulletin: IBM Engineering Lifecycle Optimization - Publishing - Connect2id Nimbus JOSE + JWT 10.0.x before 10.0.2 and 9.37.x before 9.37.4 allows a remote attacker to cause a denial of service

Summary Connect2id Nimbus JOSE + JWT 10.0.x before 10.0.2 and 9.37.x before 9.37.4 allows a remote attacker to cause a denial of service via a deeply nested JSON object supplied in a JWT claim set, because of uncontrolled recursion. Following IBM® Engineering Lifecycle Management product is...

CVE-2026-53260

Summary: CVE-2026-53260 relates to the Linux kernel tcp request-socket (reqsk) handling. The issue stems from a potential refcount underflow in __inet_csk_reqsk_queue_drop(), triggered when a reqsk is preempted between mod_timer() and refcount_set() during the queue/hash insertion path, causing t...

CVE-2026-53261

The CVE-2026-53261 issue affects the Linux kernel devlink path: when a devlink instance obtains a nested relation before registration and probe later fails, devl_unregister() does not run for an unregistered instance, leaking devlink->rel. The fix releases any pending relation from devlink_fre...
