CVE-2026-53306

CVE-2026-53306 affects the Linux kernel tty/hvc_iucv path. The issue is an off-by-one in the number of supported devices: MAX_HVC_IUCV_LINES is 8, and hvc_iucv_devices can be 0–8. When devices == 8, a path that validates against the table size can access hvc_iucv_table[8], potentially triggering ...

SUSE CVE-2026-53263

In the Linux kernel, the following vulnerability has been resolved: 6lowpan: fix off-by-one in multicast context address compression The second memcpy in lowpaniphcmcastctxaddrcompress uses &data1 as destination and &ipaddr-s6addr11 as source, but both should be offset by one: &data2 and...

CVE-2026-53263

A flaw was found in the Linux kernel's 6lowpan component. An off-by-one error during multicast context address compression can lead to the transmission of uninitialized kernel stack memory over the network. This vulnerability results in information disclosure, potentially allowing an attacker to...

CVE-2026-53088

A flaw was found in the Linux kernel's bcmgenet network driver. An off-by-one error in the bcmgenetputtxcb function, related to the writeptr handling for transmit control blocks txcb, could lead to incorrect cleanup of these blocks. This issue may result in system instability or unexpected behavi...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An off-by-one error exists in the hvc iucv tty driver. The issue occurs when the hvc iucv devices counter equals 8, which is the maximum value defined by MAX HVC IUCV LINES. Due to an...

CVE-2026-45358

A flaw was found in ImageMagick, a free and open-source software for editing and manipulating digital images. A remote attacker could exploit an off-by-one error in the meta encoder to read a single byte outside of allocated memory. This out-of-bounds read could lead to the disclosure of sensitiv...

CVE-2026-56787

RTKLIB through 2.4.3 contains an off-by-one out-of-bounds read vulnerability in the decodessr3 function at src/rtcm3.c:1446 that allows remote attackers to trigger a global buffer overflow via crafted RTCM3 SSR messages with attacker-controlled signal mode fields. Remote attackers can exploit thi...
