CVE-2026-19186 Integer underflow in IEEE 802.15.4 frame decryption leads to out-of-bounds read and write

ieee802154decipherdataframe in subsys/net/l2/ieee802154/ieee802154frame.c computed payloadlen = netpktgetlenpkt - llhdrlen - authtaglen without first checking that the received frame is at least llhdrlen + authtaglen bytes long. All three variables are uint8t, so a frame whose payload is shorter...

CVE-2026-19186

An integer underflow vulnerability exists in the ieee802154_decipher_data_frame() function within subsys/net/l2/ieee802154/ieee802154_frame.c . The software fails to verify if a received frame is long enough before subtracting header and authentication tag lengths from the total length. Because t...

kernel: RDMA/rxe: Validate pad and ICRC before payload_size() in rxe_rcv

A flaw was found in the Linux kernel's RDMA/rxe component. The rxercv function does not adequately validate the BTH pad and ICRC fields of incoming packets before calculating the payload size. A remote attacker could exploit this by sending a specially crafted short packet or a packet with a forg...

Unsigned integer underflow in wstrncat in src/port.c in wolfSSL wolfSSH from v1.4.11 through v1.5.0 on non-Windows platforms allows an authenticated remote attacker to write one out-of-bounds null byte past the end of a stack buffer by sending a crafted SFTP path. wolfSSHRealPath in src/ssh.c...

CVE-2026-83742

The wolfSSL wolfSSH library (versions 1.4.11 through 1.5.0 ) is vulnerable to an unsigned integer underflow in the wstrncat() function located in src/port.c on non-Windows platforms. This flaw occurs because wolfSSH_RealPath() in src/ssh.c incorrectly uses a remaining-size bound (outSz - curSz) i...

SUSE CVE-2026-104037

A flaw was found in SSSD. A local attacker can exploit this issue by sending a specially crafted request with an invalid packet length to the autofs responder UNIX socket. This causes an integer underflow and an out-of-bounds memory read, which can crash the responder process and result in a deni...
