| CVE-2016-9842 | Hig | 0.58 | 8.8 | 0.05 | May 23, 2017 | The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers. | ||
| CVE-2023-52810 | Hig | 0.51 | 7.8 | 0.00 | May 21, 2024 | In the Linux kernel, the following vulnerability has been resolved: fs/jfs: Add check for negative db_l2nbperpage l2nbperpage is log2(number of blks per page), and the minimum legal value should be 0, not negative. In the case of l2nbperpage being negative, an error will… | ||
| CVE-2025-32029 | Med | 0.38 | — | 0.00 | Apr 7, 2025 | ts-asn1-der is a collection of utility classes to encode ASN.1 data following DER rule. Incorrect number DER encoding can lead to denial on service for absolute values in the range 2**31 -- 2**32 - 1. The arithmetic in the numBitLen didn't take into account that values in this… | ||
| CVE-2026-5072 | Med | 0.35 | 6.5 | 0.00 | May 22, 2026 | A bitwise shift vulnerability in Zephyr's PTP subsystem allows a remote attacker to cause undefined behavior and potential system crashes. An attacker sends a crafted PTP_MSG_MANAGEMENT message to set an unvalidated negative log_announce_interval value in the port's data set.… | ||
| CVE-2026-4426 | Med | 0.35 | 6.5 | 0.00 | Mar 19, 2026 | A flaw was found in libarchive. An Undefined Behavior vulnerability exists in the zisofs decompression logic, caused by improper validation of a field (`pz_log2_bs`) read from ISO9660 Rock Ridge extensions. A remote attacker can exploit this by supplying a specially crafted ISO… | ||
| CVE-2023-3161 | Med | 0.00 | 5.5 | 0.00 | Jun 12, 2023 | A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing font->width and font->height greater than 32 to fbcon_set_font, since there are no checks in place, a shift-out-of-bounds occurs leading to undefined behavior and possible denial of service. |
