CVE-2026-56789 RTKLIB 2.4.3 - Heap Buffer Overflow and Stack Read via Oversized RINEX Epoch Satellite Count

RTKLIB through 2.4.3 contains a heap buffer overflow vulnerability in the readrnxobsb function in src/rinex.c that allows attackers to trigger memory corruption by failing to clamp satellite count values from RINEX epoch headers. Attackers can craft malicious RINEX files declaring more than 64...

CVE-2026-56789

RTKLIB 2.4.3 is affected by a heap buffer overflow and out-of-bounds stack read in readrnxobsb (src/rinex.c). The issue arises when RINEX epoch headers declare more than 64 satellites per epoch, allowing memory corruption and potentially crashing applications such as rnx2rtkp and RTKPOST. Connect...

CVE-2026-53078

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF socket operations sockops program. When a BPF sockops program accesses context fields with the same destination and source registers, certain macros fail to properly clear the destination register. This can lead to a...

CVE-2026-56766

Hydra before 9.7 contains a stack buffer overflow in the NTLM authentication handler used by SMTP, POP3, IMAP, NNTP, HTTP, HTTP-Proxy, and HTTP-Proxy-Urlenum modules when processing crafted NTLM Type-2 challenges. A malicious server can send a long domain in NTLM Type-2, overflowing a 500-byte st...

JLSEC-2026-632

Rsync versions before 3.4.3 contain an off-by-one out-of-bounds stack write vulnerability in the establishproxyconnection function in socket.c that allows network attackers to corrupt stack memory by sending a malformed HTTP proxy response. Attackers can exploit this by positioning themselves...

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...

CVE-2026-47770

The CVE-2026-47770 issue affects jq (the JSON processor) where comparing deeply nested arrays with the == operator can cause stack exhaustion via recursive structural comparison in src/jv.c (jvp_array_equal, jv_equal) and overflow in jv_cmp in src/jv_aux.c. This leads to a denial of service on at...
