| CVE-2026-39956 |
5.5 (i)
| MEDIUM | jq | jq is a command-line JSON processor. In commits after 69785bf77f86e2ea1b4a20ca86775916889e91c9, the _strindices builtin in jq's src/builtin.c passes its arguments directly to jv_string_indexes() without verifying they are strings, and jv_string_indexes() in src/jv.c relies solely on assert() checks that are stripped in release builds compiled with -DNDEBUG. This allows an attacker to crash jq trivially with input like _strindices(0), and by crafting a numeric value whose IEEE-754 bit pattern maps to a chosen pointer, achieve a controlled pointer dereference and limited memory read/probe primitive. Any deployment that evaluates untrusted jq filters against a release build is vulnerable. This issue has been patched in commit fdf8ef0f0810e3d365cdd5160de43db46f57ed03. | 2026-04-13 |
| CVE-2026-33947 |
5.5 (i)
| MEDIUM | jq | jq is a command-line JSON processor. In versions 1.8.1 and below, functions jv_setpath(), jv_getpath(), and delpaths_sorted() in jq's src/jv_aux.c use unbounded recursion whose depth is controlled by the length of a caller-supplied path array, with no depth limit enforced. An attacker can supply a JSON document containing a flat array of ~65,000 integers (~200 KB) that, when used as a path argument by a trusted jq filter, exhausts the C call stack and crashes the process with a segmentation fault (SIGSEGV). This bypass works because the existing MAX_PARSING_DEPTH (10,000) limit only protects the JSON parser, not runtime path operations where arrays can be programmatically constructed to arbitrary lengths. The impact is denial of service (unrecoverable crash) affecting any application or service that processes untrusted JSON input through jq's setpath, getpath, or delpaths builtins. This issue has been addressed in commit fb59f1491058d58bdc3e8dd28f1773d1ac690a1f. | 2026-04-13 |
| CVE-2026-32316 |
6.8 (i)
| MEDIUM | jq | jq is a command-line JSON processor. An integer overflow vulnerability exists through version 1.8.1 within the jvp_string_append() and jvp_string_copy_replace_bad functions, where concatenating strings with a combined length exceeding 2^31 bytes causes a 32-bit unsigned integer overflow in the buffer allocation size calculation, resulting in a drastically undersized heap buffer. Subsequent memory copy operations then write the full string data into this undersized buffer, causing a heap buffer overflow classified as CWE-190 (Integer Overflow) leading to CWE-122 (Heap-based Buffer Overflow). Any system evaluating untrusted jq queries is affected, as an attacker can crash the process or potentially achieve further exploitation through heap corruption by crafting queries that produce extremely large strings. The root cause is the absence of string size bounds checking, unlike arrays and objects which already have size limits. The issue has been addressed in commit e47e56d226519635768e6aab2f38f0ab037c09e5. | 2026-04-13 |
| CVE-2026-6192 |
3.3 (i)
| LOW | openjpeg | A vulnerability was identified in uclouvain openjpeg up to 2.5.4. This impacts the function opj_pi_initialise_encode in the library src/lib/openjp2/pi.c. The manipulation leads to integer overflow. The attack must be carried out locally. The exploit is publicly available and might be used. The identifier of the patch is 839936aa33eb8899bbbd80fda02796bb65068951. It is suggested to install a patch to address this issue. | 2026-04-13 |
| CVE-2026-40393 |
6.8 (i)
| MEDIUM | mesa | In Mesa before 25.3.6 and 26 before 26.0.1, out-of-bounds memory access can occur in WebGPU because the amount of to-be-allocated data depends on an untrusted party, and is then used for alloca. | 2026-04-12 |
| CVE-2026-3446 |
5.3 (i)
| MEDIUM | python | When calling base64.b64decode() or related functions the decoding process would stop after encountering the first padded quad regardless of whether there was more information to be processed. This can lead to data being accepted which may be processed differently by other implementations. Use "validate=True" to enable stricter processing of base64 data. | 2026-04-10 |
| CVE-2026-1502 |
4.9 (i)
| MEDIUM | python | CR/LF bytes were not rejected by HTTP client proxy tunnel headers or host. | 2026-04-10 |
| CVE-2026-40226 |
6.4 (i)
| MEDIUM | systemd | In nspawn in systemd 233 through 259 before 260, an escape-to-host action can occur via a crafted optional config file. | 2026-04-10 |
| CVE-2026-40225 |
6.4 (i)
| MEDIUM | systemd | In udev in systemd before 260, local root execution can occur via malicious hardware devices and unsanitized kernel output. | 2026-04-10 |
| CVE-2026-40224 |
6.7 (i)
| MEDIUM | systemd | In systemd 259 before 260, there is local privilege escalation in systemd-machined because varlink can be used to reach the root namespace. | 2026-04-10 |
