https://notcve.org/view.php?id=CVE-2024-45778
03 Mar 2025 — A stack overflow flaw was found when reading a BFS file system. A crafted BFS filesystem may lead to an uncontrolled loop, causing grub2 to crash. • https://access.redhat.com/security/cve/CVE-2024-45778 • CWE-190: Integer Overflow or Wraparound •

CVE-2024-45779 – Grub2: fs/bfs: integer overflow leads to heap oob read in the bfs parser
https://notcve.org/view.php?id=CVE-2024-45779
03 Mar 2025 — An integer overflow flaw was found in the BFS file system driver in grub2. When reading a file with an indirect extent map, grub2 fails to validate the number of extent entries to be read. A crafted or corrupted BFS filesystem may cause an integer overflow during the file reading, leading to a heap of bounds read. As a consequence, sensitive data may be leaked, or grub2 will crash. • https://access.redhat.com/security/cve/CVE-2024-45779 • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •

CVE-2024-45780 – Grub2: fs/tar: integer overflow causes heap oob write
https://notcve.org/view.php?id=CVE-2024-45780
03 Mar 2025 — A flaw was found in grub2. When reading tar files, grub2 allocates an internal buffer for the file name. However, it fails to properly verify the allocation against possible integer overflows. It's possible to cause the allocation length to overflow with a crafted tar file, leading to a heap out-of-bounds write. This flaw eventually allows an attacker to circumvent secure boot protections. • https://access.redhat.com/security/cve/CVE-2024-45780 • CWE-787: Out-of-bounds Write •

CVE-2025-0689 – Grub2: udf: heap based buffer overflow in grub_udf_read_block() may lead to arbitrary code execution
https://notcve.org/view.php?id=CVE-2025-0689
03 Mar 2025 — When reading data from disk, the grub's UDF filesystem module utilizes the user controlled data length metadata to allocate its internal buffers. In certain scenarios, while iterating through disk sectors, it assumes the read size from the disk is always smaller than the allocated buffer size which is not guaranteed. A crafted filesystem image may lead to a heap-based buffer overflow resulting in critical data to be corrupted, resulting in the risk of arbitrary code execution by-passing secure boot protecti... • https://access.redhat.com/security/cve/CVE-2025-0689 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

CVE-2025-1125 – Grub2: fs/hfs: integer overflow may lead to heap based out-of-bounds write
https://notcve.org/view.php?id=CVE-2025-1125
03 Mar 2025 — When reading data from a hfs filesystem, grub's hfs filesystem module uses user-controlled parameters from the filesystem metadata to calculate the internal buffers size, however it misses to properly check for integer overflows. A maliciouly crafted filesystem may lead some of those buffer size calculation to overflow, causing it to perform a grub_malloc() operation with a smaller size than expected. As a result the hfsplus_open_compressed_real() function will write past of the internal buffer length. This... • https://access.redhat.com/security/cve/CVE-2025-1125 • CWE-787: Out-of-bounds Write •

CVE-2025-26601 – Xorg: xwayland: use-after-free in syncinittrigger()
https://notcve.org/view.php?id=CVE-2025-26601
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 •

CVE-2025-26600 – Xorg: xwayland: use-after-free in playreleasedevents()
https://notcve.org/view.php?id=CVE-2025-26600
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 •

CVE-2025-26599 – Xorg: xwayland: use of uninitialized pointer in compredirectwindow()
https://notcve.org/view.php?id=CVE-2025-26599
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 •

CVE-2025-26598 – Xorg: xwayland: out-of-bounds write in createpointerbarrierclient()
https://notcve.org/view.php?id=CVE-2025-26598
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 •

CVE-2025-26597 – Xorg: xwayland: buffer overflow in xkbchangetypesofkey()
https://notcve.org/view.php?id=CVE-2025-26597
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 •
