CVE-2026-89551
A flaw was found in the Linux kernel's SUNRPC subsystem, specifically within the xdrbuftrim function. This vulnerability occurs when xdrbuftrim attempts to reduce the size of an XDR buffer. If the buffer's length is smaller than the amount being trimmed, an integer underflow can occur, causing th...
CVE-2026-89551
CVE-2026-89551 is a CRITICAL (CVSS 9.8) integer underflow in the Linux kernel's SUNRPC subsystem. The xdr_buf_trim() function subtracts consumed bytes from buf->len without clamping, so when called from gss_krb5_unwrap_v2() with a small wire-derived buf->len while page-scale iov_lens are pr...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: net/ipv6: ioam6: This vulnerability prevents a wrap-around issue with the schema length during the trace filling process. The ioam6fillTraceData function stores the schema contribution to the trace length in an u8 type variable...
CVE-2026-64548 bpf, sockmap: reject overflowing copy + len in bpf_msg_push_data()
In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: reject overflowing copy + len in bpfmsgpushdata When the scatterlist ring is full or nearly full, bpfmsgpushdata enters a copy fallback path and computes copy + len for the page allocation size. Since len comes from...
JLSEC-2026-715 An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name (SAN)...
An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect...
CVE-2026-38427
An issue in fetchjpg in xdrv10scripter.ino in Tasmota through 15.3.0.3 allows a remote attacker to cause heap buffer overflow. The Content-Length from a JPEG stream is stored in a uint16t variable; values above 65535 wrap around, causing allocation of a smaller buffer than the data actually read...
CVE-2026-38427
CVE-2026-38427 : In Tasmota up to 15.3.0.3, fetch_jpg() in xdrv_10_scripter.ino stores the JPEG Content-Length in a uint16_t. Values > 65535 wrap around, causing allocation of a smaller heap buffer than the data read and a heap buffer overflow. This enables a remote attacker over the network t...

CVE-2026-31659
In the Linux kernel, the following vulnerability has been resolved: batman-adv: reject oversized global TT response buffers batadvttpreparetvlvglobaldata builds the allocation length for a global TT response in 16-bit temporaries. When a remote originator advertises a large enough global TT, the ...
CVE-2026-31659
The CVE-2026-31659 issue affects the batman-adv component in the Linux kernel. batadv_tt_prepare_tvlv_global_data() computes a 16‑bit allocation length for a global TT response; if a remote originator advertises a large TT, the TT payload length plus VLAN offset can exceed 65,535 and wrap before ...
CVE-2026-5188
An integer underflow issue exists in wolfSSL when parsing the Subject Alternative Name SAN extension of X.509 certificates. A malformed certificate can specify an entry length larger than the enclosing sequence, causing the internal length counter to wrap during parsing. This results in incorrect...
