Cross-site scripting (XSS) vulnerability due to improper input validation. The following products are affected: Acronis Cyber Protect 17 (Linux, Windows) before build 42587.
CVE-2026-63573 2 Bouncycastle, Legion Of The Bouncy Castle Inc. 2 Bc-csharp, Bc-csharp 2026-10-28 7.5 High
Observable discrepancy in the CMS RSA PKCS#1 v1.5 key-transport unwrap (KeyTransRecipientInformation.UnwrapKey) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote attacker who holds a captured CMS EnvelopedData message, and who can submit many modified messages to an application that decrypts them with the recipient's RSA private key and reveals how decryption failed, to recover the captured message's content-encryption key and so its content, via a Bleichenbacher-style adaptive chosen-ciphertext attack, because a key-transport ciphertext with invalid PKCS#1 v1.5 padding is rejected during unwrap with a distinct "bad padding in message." CmsException instead of being replaced by a random key, so it can be told apart from a correctly padded ciphertext, which fails only later at content decryption.
CVE-2026-70164 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-28 7 High
Use after free in Windows TCP/IP allows an authorized attacker to elevate privileges locally.
CVE-2026-70168 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-28 7 High

CVE-2026-63574 2 Bouncycastle, Legion Of The Bouncy Castle Inc. 2 Bc-csharp, Bc-csharp 2026-10-28 7.5 High
Memory allocation with excessive size value in the OpenPGP signature and user attribute subpacket parsers (SignatureSubpacketsParser.ReadPacket, UserAttributeSubpacketsParser.ReadPacket) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote, unauthenticated attacker who can supply a crafted OpenPGP public key, certificate or signature to cause a denial of service (OutOfMemoryException or memory exhaustion in the parsing process) via a subpacket header using the five-octet length form, because the declared length was used to size the subpacket buffer with no upper bound and without being compared with the size of the enclosing subpacket area or packet, so a few bytes of input could demand an allocation of up to about 2 GB before any subpacket data was read.
CVE-2026-70169 1 Microsoft 20 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 17 more 2026-10-28 7 High

Untrusted pointer dereference in Windows NTFS allows an authorized attacker to elevate privileges locally.
CVE-2026-93516 1 X.org 3 X Server, Xorg-x11-server, Xwayland 2026-10-28 5.5 Medium
A use-after-free caused by lack of lifecycle management when adding / removing XInput master devices in X.org X Server before 21.1.25 and XWayland before 24.1.14 could be used by authenticated X Clients to crash the X server or potentially execute code in X server context.

Sensitive information disclosure due to improper authorization. The following products are affected: Acronis Cyber Protect 17 (Linux, Windows) before build 42587.
CVE-2026-87100 1 Acronis 1 Acronis Cyber Protect 17 2026-10-28 N/A
Protection mechanism failure due to missing binary hardening in Linux executables. The following products are affected: Acronis Cyber Protect 17 (Linux) before build 42587.
CVE-2026-99102 1 Linux 2 Linux, Linux Kernel 2026-10-28 3.3 Low
In the Linux kernel, the following vulnerability has been resolved: ntfs: take invalidate_lock in ntfs_setattr_size() ntfs_setattr_size() updates i_size and resizes the on-disk attribute without holding mapping->invalidate_lock. Page faults take the lock shared, so a fault racing the resize can resolve a VCN against the transient runlist state of ntfs_non_resident_attr_expand() and fail with a spurious SIGBUS, and can interleave with the size-change epilogue (truncate_pagecache(), i_size_write(), pagecache_isize_extended()). Take invalidate_lock exclusively around the whole resize after inode_dio_wait(), matching the fallocate path and other filesystems such as xfs, which wraps truncate in its mmaplock (= invalidate_lock).

CVE-2026-93515 1 X.org 3 X Server, Xorg-x11-server, Xwayland 2026-10-28 6.1 Medium
A use-after-free in present_clear_window_notifies() in the X.org X Server before 21.1.25 and X Wayland before 24.1.14 could be used by malicious X clients to crash or potentially execute code in the X server context.
