25 Feb 2025 — A use-after-free flaw was found in X.Org and Xwayland. When changing an alarm, the values of the change mask are evaluated one after the other, changing the trigger values as requested, and eventually, SyncInitTrigger() is called. If one of the changes triggers an error, the function will return early, not adding the new sync object, possibly causing a use-after-free when the alarm eventually triggers. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server... • https://access.redhat.com/security/cve/CVE-2025-26601 • CWE-416: Use After Free •

25 Feb 2025 — 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. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the handling of devi... • https://access.redhat.com/security/cve/CVE-2025-26600 • CWE-416: Use After Free •

25 Feb 2025 — An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obta... • https://access.redhat.com/security/cve/CVE-2025-26599 • CWE-824: Access of Uninitialized Pointer •

25 Feb 2025 — An out-of-bounds write flaw was found in X.Org and Xwayland. The function GetBarrierDevice() searches for the pointer device based on its device ID and returns the matching value, or supposedly NULL, if no match was found. However, the code will return the last element of the list if no matching device ID is found, which can lead to out-of-bounds memory access. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the abilit... • https://access.redhat.com/security/cve/CVE-2025-26598 • CWE-787: Out-of-bounds Write •

25 Feb 2025 — A buffer overflow flaw was found in X.Org and Xwayland. If XkbChangeTypesOfKey() is called with a 0 group, it will resize the key symbols table to 0 but leave the key actions unchanged. If the same function is later called with a non-zero value of groups, this will cause a buffer overflow because the key actions are of the wrong size. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged... • https://access.redhat.com/security/cve/CVE-2025-26597 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

25 Feb 2025 — A heap overflow flaw was found in X.Org and Xwayland. The computation of the length in XkbSizeKeySyms() differs from what is written in XkbWriteKeySyms(), which may lead to a heap-based buffer overflow. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the XkbSizeKeySyms function.

25 Feb 2025 — A buffer overflow flaw was found in X.Org and Xwayland. The code in XkbVModMaskText() allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and would copy the data regardless of the size. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit t... • https://access.redhat.com/security/cve/CVE-2025-26595 • CWE-121: Stack-based Buffer Overflow •

25 Feb 2025 — 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. This vulnerability allows local attackers to escalate privileges on affected installations of X.Org Server. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the h... • https://access.redhat.com/security/cve/CVE-2025-26594 • CWE-416: Use After Free •

19 Feb 2025 — A flaw was found in grub2. During the network boot process, when trying to search for the configuration file, grub copies data from a user controlled environment variable into an internal buffer using the grub_strcpy() function. During this step, it fails to consider the environment variable length when allocating the internal buffer, resulting in an out-of-bounds write. If correctly exploited, this issue may result in remote code execution through the same network segment grub is searching for the boot inf... • https://access.redhat.com/security/cve/CVE-2025-0624 • CWE-787: Out-of-bounds Write •

22 Jan 2025 — A vulnerability was found in `podman build` and `buildah.` This issue occurs in a container breakout by using --jobs=2 and a race condition when building a malicious Containerfile. SELinux might mitigate it, but even with SELinux on, it still allows the enumeration of files and directories on the host. An update for the container-tools:rhel8 module is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support, Red Hat Enterprise Linux 8.6 Update Services for SAP Solutions, and R... • https://access.redhat.com/security/cve/CVE-2024-11218 • CWE-269: Improper Privilege Management •
