https://notcve.org/view.php?id=CVE-2023-6536
07 Feb 2024 — A flaw was found in the Linux kernel's NVMe driver. This issue may allow an unauthenticated malicious actor to send a set of crafted TCP packages when using NVMe over TCP, leading the NVMe driver to a NULL pointer dereference in the NVMe driver, causing kernel panic and a denial of service. Se encontró una falla en el controlador NVMe del kernel de Linux. Este problema puede permitir que un actor malicioso no autenticado envíe un conjunto de paquetes TCP manipulados cuando usa NVMe sobre TCP, lo que lleva a... • https://access.redhat.com/errata/RHSA-2024:0723 • CWE-476: NULL Pointer Dereference •

CVE-2023-5455 – Ipa: invalid csrf protection
https://notcve.org/view.php?id=CVE-2023-5455
10 Jan 2024 — A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing alrea... • https://access.redhat.com/errata/RHSA-2024:0137 • CWE-352: Cross-Site Request Forgery (CSRF) •

CVE-2023-3972 – Insights-client: unsafe handling of temporary files and directories
https://notcve.org/view.php?id=CVE-2023-3972
01 Nov 2023 — A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could ... • https://access.redhat.com/errata/RHSA-2023:6264 • CWE-379: Creation of Temporary File in Directory with Insecure Permissions CWE-668: Exposure of Resource to Wrong Sphere •

CVE-2023-3899 – Subscription-manager: inadequate authorization of com.redhat.rhsm1 d-bus interface allows local users to modify configuration
https://notcve.org/view.php?id=CVE-2023-3899
23 Aug 2023 — A vulnerability was found in subscription-manager that allows local privilege escalation due to inadequate authorization. The D-Bus interface com.redhat.RHSM1 exposes a significant number of methods to all users that could change the state of the registration. By using the com.redhat.RHSM1.Config.SetAll() method, a low-privileged local user could tamper with the state of the registration, by unregistering the system or by changing the current entitlements. This flaw allows an attacker to set arbitrary confi... • https://access.redhat.com/errata/RHSA-2023:4701 • CWE-285: Improper Authorization CWE-863: Incorrect Authorization •

CVE-2023-0494 – X.Org Server DeepCopyPointerClasses Use-After-Free Local Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2023-0494
07 Feb 2023 — A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the abilit... • https://bugzilla.redhat.com/show_bug.cgi?id=2165995 • CWE-416: Use After Free •

CVE-2022-2601 – grub2: Buffer overflow in grub_font_construct_glyph() can lead to out-of-bound write and possible secure boot bypass
https://notcve.org/view.php?id=CVE-2022-2601
16 Nov 2022 — A buffer overflow was found in grub_font_construct_glyph(). A malicious crafted pf2 font can lead to an overflow when calculating the max_glyph_size value, allocating a smaller than needed buffer for the glyph, this further leads to a buffer overflow and a heap based out-of-bounds write. An attacker may use this vulnerability to circumvent the secure boot mechanism. Se encontró un desbordamiento del búfer en grub_font_construct_glyph(). Una fuente pf2 manipulada maliciosamente puede provocar un desbordamien... • https://bugzilla.redhat.com/show_bug.cgi?id=2112975#c0 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVE-2021-3695 – grub2: Crafted PNG grayscale images may lead to out-of-bounds write in heap
https://notcve.org/view.php?id=CVE-2021-3695
20 Jun 2022 — A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw af... • https://bugzilla.redhat.com/show_bug.cgi?id=1991685 • CWE-787: Out-of-bounds Write •

CVE-2021-3696 – grub2: Crafted PNG image may lead to out-of-bound write during huffman table handling
https://notcve.org/view.php?id=CVE-2021-3696
20 Jun 2022 — A heap out-of-bounds write may heppen during the handling of Huffman tables in the PNG reader. This may lead to data corruption in the heap space. Confidentiality, Integrity and Availablity impact may be considered Low as it's very complex to an attacker control the encoding and positioning of corrupted Huffman entries to achieve results such as arbitrary code execution and/or secure boot circumvention. This flaw affects grub2 versions prior grub-2.12. Puede producirse una escritura fuera de límites de la p... • https://bugzilla.redhat.com/show_bug.cgi?id=1991686 • CWE-787: Out-of-bounds Write •
