CVE-2023-1513 – kernel: KVM: information leak in KVM_GET_DEBUGREGS ioctl on 32-bit systems
https://notcve.org/view.php?id=CVE-2023-1513
A flaw was found in KVM. When calling the KVM_GET_DEBUGREGS ioctl, on 32-bit systems, there might be some uninitialized portions of the kvm_debugregs structure that could be copied to userspace, causing an information leak. • https://bugzilla.redhat.com/show_bug.cgi?id=2179892 https://github.com/torvalds/linux/commit/2c10b61421a28e95a46ab489fd56c0f442ff6952 https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://lore.kernel.org/kvm/20230214103304.3689213-1-gregkh%40linuxfoundation.org https://access.redhat.com/security/cve/CVE-2023-1513 • CWE-665: Improper Initialization •
CVE-2023-1281 – UAF in Linux kernel's tcindex (traffic control index filter) implementation
https://notcve.org/view.php?id=CVE-2023-1281
Use After Free vulnerability in Linux kernel traffic control index filter (tcindex) allows Privilege Escalation. The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext. A local attacker user can use this vulnerability to elevate its privileges to root. This issue affects Linux Kernel: from 4.14 before git commit ee059170b1f7e94e55fa6cadee544e176a6e59c2. A use-after-free vulnerability was found in the traffic control index filter (tcindex) in the Linux kernel. The imperfect hash area can be updated while packets are traversing. • http://www.openwall.com/lists/oss-security/2023/04/11/3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=ee059170b1f7e94e55fa6cadee544e176a6e59c2 https://kernel.dance/#ee059170b1f7e94e55fa6cadee544e176a6e59c2 https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://lists.debian.org/debian-lts-announce/2023/05/msg00006.html https://security.netapp.com/advisory/ntap-20230427-0004 https://access.redhat.com/security/cve/CVE-2023-1281 https://bugzilla.r • CWE-416: Use After Free •
CVE-2023-0386 – kernel: FUSE filesystem low-privileged user privileges escalation
https://notcve.org/view.php?id=CVE-2023-0386
A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system. • https://github.com/sxlmnwb/CVE-2023-0386 https://github.com/xkaneiki/CVE-2023-0386 https://github.com/chenaotian/CVE-2023-0386 https://github.com/Fanxiaoyao66/CVE-2023-0386 https://github.com/veritas501/CVE-2023-0386 https://github.com/3yujw7njai/CVE-2023-0386 https://github.com/puckiestyle/CVE-2023-0386 https://github.com/churamanib/CVE-2023-0386 https://github.com/letsr00t/CVE-2023-0386 https://github.com/EstamelGG/CVE-2023-0386-libs http://packetstormsecurity.com/fi • CWE-282: Improper Ownership Management •
CVE-2022-48425
https://notcve.org/view.php?id=CVE-2022-48425
In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT flags before replaying logs. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=467333af2f7b95eeaa61a5b5369a80063cd971fd https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/fs/ntfs3?id=467333af2f7b95eeaa61a5b5369a80063cd971fd https://security.netapp.com/advisory/ntap-20230413-0006 • CWE-763: Release of Invalid Pointer or Reference •
CVE-2023-28466 – kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference
https://notcve.org/view.php?id=CVE-2023-28466
do_tls_getsockopt in net/tls/tls_main.c in the Linux kernel through 6.2.6 lacks a lock_sock call, leading to a race condition (with a resultant use-after-free or NULL pointer dereference). A use-after-free flaw was found in the do_tls_getsockopt function in net/tls/tls_main.c in the Transport Layer Security (TLS) in the Network subcompact in the Linux kernel. This flaw allows an attacker to cause a NULL pointer dereference problem due to a race condition. • https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?id=49c47cc21b5b7a3d8deb18fc57b0aa2ab1286962 https://lists.debian.org/debian-lts-announce/2023/05/msg00005.html https://security.netapp.com/advisory/ntap-20230427-0006 https://access.redhat.com/security/cve/CVE-2023-28466 https://bugzilla.redhat.com/show_bug.cgi?id=2179000 • CWE-416: Use After Free CWE-476: NULL Pointer Dereference •
