Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: xen/privcmd: Fixed a possible warning in privcmdioctlmmapresource. Since ‘kdata.num’ is a user-controlled data, if the user attempts to allocate memory larger than MAXORDER, then kcalloc will fail. This will also generate a stack...

CVE-2026-89533

In the Linux kernel, the following vulnerability has been resolved: svcrdma: Fix offset arithmetic in readchunkrange svcrdmareadchunkrange walks a Read chunk's segment list to build a sub-range starting at byte offset and spanning length bytes for a Position-Zero or Call chunk. Two arithmetic...

CVE-2026-63384

A flaw was found in Libevent. An incorrect integer conversion in the evtagunmarshalheader function allows a remote attacker to provide a specially crafted payload length. This can lead to a wrapped large allocation request, resulting in a denial of service DoS for the affected system. Mitigation...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Rejects undersized DACLs before parsing ACEs The parsedacl function limits the number of attacker-controlled ACE entries by comparing it with the minimum number of ACE entries that fit within the DACL size. The DACL size...

CVE-2026-58060 HSS public-key level count unbounded, enabling huge allocation on verify

In Bouncy Castle for Java before 1.85, HSS public-key level count unbounded, enabling huge allocation on verify. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS BC-FJA before bc-fips 2.0.2 2.0.X series and 2.1.3 2.1.X series...

CVE-2026-55768 GoAccess WebSocket Server: Signed 32 bit truncation of the 64 bit frame length causes a remote pre-authentication denial of service

GoAccess is a real-time web log analyzer and interactive viewer that runs in a terminal in nix systems or through the browser. Prior to version 1.11, the built-in WebSocket server narrows a 64-bit extended frame length into the signed 32-bit WSFrame.payloadlen field before enforcing the maximum...

CVE-2026-64508

In the Linux kernel, the following vulnerability has been resolved: bpf: Support for hardening against JIT spraying The BPF JIT allocator packs many small programs into larger executable allocations and reuses space within those allocations as programs are loaded and freed. When fresh code is...

EUVD-2026-46392

CImg Library is a C++ library for image processing. Prior to version 4.0.0 in loadanalyze, the headersize field is read as an unsigned int from the first 4 bytes of an Analyze/NIfTI file and passed directly to new unsigned charheadersize without being bounded against the actual file size. A value...

CVE-2026-55213

CVE-2026-55213 (h2o HTTP server) – Affected component: lib/http3/qpack.c, invoked while processing a QPACK instruction over HTTP/3. Root cause: on-stack allocation of a large buffer (up to ~800 KB) via alloca, exceeding default musl libc pthread stack size, leading to a segmentation fault when to...

CVE-2026-14454

Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed. Imager mishandled large EXIF IFD entry count values, treating them as negative numbers. This could lead to an attempt to allocate a block nearly the size of the address space, which fails and kills the process. ...

Netty: SNI handler pre-allocates up to 16 MiB from nine attacker bytes

SslClientHelloHandler.decode reads the 24-bit TLS handshake length and, when the ClientHello does not fit in the first record, eagerly allocates ctx.alloc.bufferhandshakeLength line 161. The guard at line 140 is handshakeLength maxClientHelloLength && maxClientHelloLength != 0, and the...

CVE-2026-42583

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Lz4FrameDecoder allocates a ByteBuf of size decompressedLength up to 32 MB per block before LZ4 runs. A peer only needs a 21-byte header plus compressedLength payload bytes - 22 bytes if...

PT-2026-36336

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the ksmbd module where the smb inherit dacl function trusts the num aces value from a parent directory's DACL xattr to determine the size of a heap allocation. An...
