Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: configfs: Fixed OOB read on empty string write When writing an empty string to either ‘qwsign’ or ‘landingPage’ sysfs attributes, the store functions attempt to access pagel – 1 before verifying that the length ‘l’ i...
Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: configfs: Prevent OOB read/write in usbstringcopy The string ‘s’ provided by the user space could easily have a length of zero. If this is left unchecked, it will first result in an OOB read in the form of if str0 - ...
JLSEC-2026-781
A flaw was found in libssh. The API function sshgethexa is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI Generic Security Service Application Program Interface authentication if the server's logging verbosity is se...
CVE-2026-49852
Summary: CVE-2026-49852 affects the Python library joserfc. Prior to version 1.6.8, joserfc.jwt.decode can accept attacker-forged HS256/HS384/HS512 tokens if the verification key is empty or None, enabling potential authentication bypass when the configured secret resolves to an empty string. The...
CVE-2026-53029
A flaw was found in the Linux kernel's ntfs3 filesystem driver. This vulnerability occurs due to an uninitialized local variable lcn when handling zero-length data during I/O operations. An attacker could potentially exploit this flaw to cause a denial of service or information disclosure due to...
Astra Linux – Vulnerability in libssh
A flaw was discovered in libssh. The API function sshgethexa is vulnerable to a denial-of-service attack when processing zero-length inputs. This vulnerability can be exploited remotely by an attacker during GSSAPI Generic Security Service Application Program Interface authentication, if the...
kernel: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()
A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackh323 module. This vulnerability occurs in the DecodeQ931 function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value...
