CVE-2026-102555 [HIGH] CWE-125 CVE-2026-102555: A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the returned GBytes. This can lead to

CVE-2018-1087 [HIGH] CWE-250 CVE-2018-1087: kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel kernel KVM before versions kernel 4.16, kernel 4.16-rc7, kernel 4.17-rc1, kernel 4.17-rc2 and kernel 4.17-rc3 is vulnerable to a flaw in the way the Linux kernel's KVM hypervisor handled exceptions delivered after a stack switch operation via Mov SS or Pop SS instructions. During the stack switch operation, the processor did not deliver interrupts and e

CVE-2014-3673 [HIGH] CWE-20 CVE-2014-3673: The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c.

CVE-2020-14346 [HIGH] CWE-191 CVE-2020-14346: A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension pro A flaw was found in xorg-x11-server before 1.20.9. An integer underflow in the X input extension protocol decoding in the X server may lead to arbitrary access of memory contents. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2025-26600 [HIGH] CWE-416 CVE-2025-26600: A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, A use-after-free flaw was found in X.Org and Xwayland. When a device is removed while still frozen, the events queued for that device remain while the device is freed. Replaying the events will cause a use-after-free.

CVE-2025-26594 [HIGH] CWE-416 CVE-2025-26594: A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server A use-after-free flaw was found in X.Org and Xwayland. The root cursor is referenced in the X server as a global variable. If a client frees the root cursor, the internal reference points to freed memory and causes a use-after-free.

CVE-2022-0330 [HIGH] CWE-281 CVE-2022-0330: A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU.

CVE-2026-58380 [HIGH] CWE-193 CVE-2026-58380: A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pn A flaw was found in GIMP's PNM file format parser. When parsing a specially crafted PNM file, the pnmscanner_gettoken() function writes a null terminator one byte past the end of a stack-allocated buffer due to an off-by-one error in the loop boundary check. This could lead to memory corruption, potentially resulting in denial of service or arbitrary

CVE-2024-0562 [HIGH] CWE-416 CVE-2024-0562: A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is calle A use-after-free flaw was found in the Linux Kernel. When a disk is removed, bdi_unregister is called to stop further write-back and waits for associated delayed work to complete. However, wb_inode_writeback_end() may schedule bandwidth estimation work after this has completed, which can result in the timer attempting to access the recently freed bdi_wr
