CVE-2026-58050

libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation numattrs sizeoflibssh2publickeyattribute without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer. A malicious S...

CVE-2026-58050 libssh2 - Integer Overflow in publickey Subsystem Attribute Allocation

libssh2 through 1.11.1 reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response and uses it in the allocation numattrs sizeoflibssh2publickeyattribute without bounds checking, so on 32-bit platforms the multiplication overflows to an undersized buffer.

CVE-2026-58050

CVE-2026-58050 affects libssh2 up to 1.11.1. The publickey subsystem reads an attacker-controlled 32-bit attribute count and uses it in the allocation num_attrs * sizeof(libssh2_publickey_attribute) without bounds checking. On 32-bit platforms, this multiplication can overflow, producing an under...

PT-2026-53082

Name of the Vulnerable Software and Affected Versions libssh2 versions prior to 1.11.2 Description An integer overflow occurs when the software reads an attacker-controlled 32-bit attribute count from a publickey-subsystem response. This value is used in the allocation num attrs sizeoflibssh2...

CVE-2026-53199

A flaw was found in the Linux kernel's Hyper-V network virtual service client hvnetvsc component. This vulnerability occurs in the netvsccopytosendbuf function, where incorrect memory mapping of page buffer entries can lead to a system fault. Specifically, on 32-bit x86 systems with high memory...

CVE-2026-53015

A flaw was found in the Linux kernel's erofs filesystem. On 32-bit platforms, the lcn variable, used for logical cluster numbers, was defined as a 32-bit integer. This could lead to truncation when calculating offsets larger than 4 Gigabytes GiB, potentially causing incorrect data handling within...

CVE-2026-53047

A flaw was found in the Linux kernel's EFI Extensible Firmware Interface capsule loader. An incorrect size calculation during memory reallocation for physical addresses can lead to an undersized buffer. This issue, specifically on 32-bit systems with Physical Address Extension PAE, may result in ...

CVE-2026-54679

jq is a command-line JSON processor. Prior to 1.8.2, on 32bit system, jvpstringappend has a chance of integer/multiple overflowing and then causing a massive buffer overrun. This vulnerability is fixed in 1.8.2...

PT-2026-52519

Name of the Vulnerable Software and Affected Versions jq versions prior to 1.8.2 Description On 32-bit systems, the jvp string append function is susceptible to integer or multiplication overflow, which can lead to a significant buffer overrun. A buffer overrun occurs when a program writes more...

CVE-2026-52967

In the Linux kernel, the following vulnerability has been resolved: smb/client: fix possible infinite loop and oob read in symlinkdata On 32-bit architectures, the infinite loop is as follows: len = p-ErrorDataLength == 0xfffffff8 u8 next = p-ErrorContextData + len next == p On 32-bit...

CVE-2026-53015

In the Linux kernel’s EROFS code, the lcn field was typed as unsigned long (or unsigned int), which is 32-bit on 32-bit platforms, causing (lcn <

EUVD-2026-38730

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: fix OOB read in compatmtwfromuser Luxiao Xu says: The function compatmtwfromuser converts ebtables extensions from 32-bit user structures to kernel native structures. However, it lacks proper validation of th...

CVE-2026-56367 ImageMagick - Heap Out-of-Bounds Read in PSB RLE Decoding

ImageMagick before 7.1.2-15 and 6.9.x before 6.9.13-40 contains an integer overflow in the PSB PSD v2 RLE decoding path ReadPSDChannelRLE in coders/psd.c that causes a heap out-of-bounds read on 32-bit builds. Processing a crafted PSB file can lead to information disclosure or a crash...

CVE-2026-56367

ImageMagick before 7.1.2-15 and 6.9.x before 6.9.13-40 contain an integer overflow in the PSB (PSD v2) RLE decoding path (ReadPSDChannelRLE in coders/psd.c) that causes a heap out-of-bounds read on 32-bit builds. Processing a crafted PSB file can lead to information disclosure or a crash. Affecte...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: The current directory offset allocator based on mtreealloccyclic stores the next offset value to be returned in octx-nextoffset. This mechanism typically returns values that increase monotonically over time. Eventually, however,...
