CVE-2026-54578 mport verify can compare stale checksum data after hashing failures

mport is the MidnightBSD Package Manager. Prior to 2.7.8, mportverifypackage in libmport/verify.c could continue after MD5File or SHA256File failed and compare an expected checksum with stale data in the hash buffer rather than a newly computed digest. An attacker able to influence an installed...

In Wireshark versions 3.2.0 to 3.2.6, 3.0.0 to 3.0.13, and 2.6.0 to 2.6.20, the TCP dissector could crash. This issue was addressed in the epan/dissectors/packet-tcp.c file by changing the handling of the invalid 0xFFFF checksum...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftpayload: The offset and length are sanitized before calling skbchecksum. If the access to the sum of the offset and length exceeds the skbuff length, then skbchecksum triggers a BUGON. skbchecksum internally subtrac...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15

A issue was discovered in the Linux kernel before version 6.3.3. There is an out-of-bounds read in the crc16 function in lib/crc16.c when called from fs/ext4/super.c, because ext4groupdesccsum does not properly check an offset. NOTE: This issue is disputed by third parties, as the kernel is not...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: net: gso: It is now forbidden to perform IPv6 TSO with extensions on devices that only have IPV6CSUM available. When performing Generic Segmentation Offload GSO on an IPv6 packet that contains extension headers, the kernel...

Astra Linux - Vulnerability in Golang-1.23

A malicious module proxy can exploit a flaw in the go command’s validation of module checksums to bypass the checksum database validation process. This vulnerability affects any user who uses a trusted module proxy GOMODPROXY or a checksum database GOSUMDB. A malicious module proxy can serve...
