TencentOS Server 4: jq (TSSA-2026:0863)

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0863 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...

jq decNumberFromString Buffer Overflow DoS

The vulnerability of the decNumberFromString function in the jq JSON processing tool is related to integer overflow. Exploiting this vulnerability could allow an attacker to cause a service failure...

SUSE CVE-2026-43894

jq is a command-line JSON processor. In 1.8.1 and earlier, when decNumberFromString is given a number literal of INTMAX-1 2147483646 digits, the D2U macro overflows during signed-int arithmetic. The wrapped negative value bypasses the heap-allocation size check, causes the function to use a 30-by...

CVE-2026-43894

CVE-2026-43894 affects jq up to version 1.8.1 and earlier. The root cause is a signed-int overflow in decNumberFromString’s D2U() macro, causing a wrap to a negative value, bypassing the heap-size check and using a 30-byte stack buffer. This results in writing ~715 million 16-bit units (≈1.4 GiB)...
