| CVE-2026-23233 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid mapping wrong physical block for swapfile Xiaolong Guo reported a f2fs bug in bugzilla [1] [1] https://bugzilla.kernel.org/show_bug.cgi?id=220951 Quoted: "When using stress-ng's swap stress test on F2FS filesystem with kernel 6.6+, the system experiences data corruption leading to either: 1 dm-verity corruption errors and device reboot 2 F2FS node corruption errors and boot hangs The issue occurs specifically when: 1 Using F2FS filesystem (ext4 is unaffected) 2 Swapfile size is less than F2FS section size (2MB) 3 Swapfile has fragmented physical layout (multiple non-contiguous extents) 4 Kernel version is 6.6+ (6.1 is unaffected) The root cause is in check_swap_activate() function in fs/f2fs/data.c. When the first extent of a small swapfile (< 2MB) is not aligned to section boundaries, the function incorrectly treats it as the last extent, failing to map subsequent extents. This results in incorrect swap_extent creation where only the first extent is mapped, causing subsequent swap writes to overwrite wrong physical locations (other files' data). Steps to Reproduce 1 Setup a device with F2FS-formatted userdata partition 2 Compile stress-ng from https://github.com/ColinIanKing/stress-ng 3 Run swap stress test: (Android devices) adb shell "cd /data/stressng; ./stress-ng-64 --metrics-brief --timeout 60 --swap 0" Log: 1 Ftrace shows in kernel 6.6, only first extent is mapped during second f2fs_map_blocks call in check_swap_activate(): stress-ng-swap-8990: f2fs_map_blocks: ino=11002, file offset=0, start blkaddr=0x43143, len=0x1 (Only 4KB mapped, not the full swapfile) 2 in kernel 6.1, both extents are correctly mapped: stress-ng-swap-5966: f2fs_map_blocks: ino=28011, file offset=0, start blkaddr=0x13cd4, len=0x1 stress-ng-swap-5966: f2fs_map_blocks: ino=28011, file offset=1, start blkaddr=0x60c84b, len=0xff The problematic code is in check_swap_activate(): if ((pblock - SM_I(sbi)->main_blkaddr) % blks_per_sec || nr_pblocks % blks_per_sec || !f2fs_valid_pinned_area(sbi, pblock)) { bool last_extent = false; not_aligned++; nr_pblocks = roundup(nr_pblocks, blks_per_sec); if (cur_lblock + nr_pblocks > sis->max) nr_pblocks -= blks_per_sec; /* this extent is last one */ if (!nr_pblocks) { nr_pblocks = last_lblock - cur_lblock; last_extent = true; } ret = f2fs_migrate_blocks(inode, cur_lblock, nr_pblocks); if (ret) { if (ret == -ENOENT) ret = -EINVAL; goto out; } if (!last_extent) goto retry; } When the first extent is unaligned and roundup(nr_pblocks, blks_per_sec) exceeds sis->max, we subtract blks_per_sec resulting in nr_pblocks = 0. The code then incorrectly assumes this is the last extent, sets nr_pblocks = last_lblock - cur_lblock (entire swapfile), and performs migration. After migration, it doesn't retry mapping, so subsequent extents are never processed. " In order to fix this issue, we need to lookup block mapping info after we migrate all blocks in the tail of swapfile. | ||||

| CVE-2026-3849 | 1 Wolfssl | 1 Wolfssl | 2026-04-15 | 9.8 Critical |
| Stack Buffer Overflow in wc_HpkeLabeledExtract via Oversized ECH Config. A vulnerability existed in wolfSSL 5.8.4 ECH (Encrypted Client Hello) support, where a maliciously crafted ECH config could cause a stack buffer overflow on the client side, leading to potential remote execution and client program crash. This could be exploited by a malicious TLS server supporting ECH. Note that ECH is off by default, and is only enabled with enable-ech. | ||||
| CVE-2026-33144 | 1 Gpac | 1 Gpac | 2026-04-15 | 5.8 Medium |
| GPAC is an open-source multimedia framework. Prior to commit 86b0e36, a heap-based buffer overflow (write) vulnerability was discovered in GPAC MP4Box. The vulnerability exists in the gf_xml_parse_bit_sequence_bs function in utils/xml_bin_custom.c when processing a crafted NHML file containing malicious <BS> (BitSequence) elements. An attacker can exploit this by providing a specially crafted NHML file, causing an out-of-bounds write on the heap. This issue has been via commit 86b0e36. | ||||
| CVE-2026-27853 | 1 Powerdns | 1 Dnsdist | 2026-04-15 | 5.9 Medium |
| An attacker might be able to trigger an out-of-bounds write by sending crafted DNS responses to a DNSdist using the DNSQuestion:changeName or DNSResponse:changeName methods in custom Lua code. In some cases the rewritten packet might become larger than the initial response and even exceed 65535 bytes, potentially leading to a crash resulting in denial of service. | ||||
| CVE-2026-35559 | 4 Amazon, Apple, Linux and 1 more | 5 Amazon Athena Odbc Driver, Athena Odbc, Macos and 2 more | 2026-04-15 | 6.5 Medium |
| Out-of-bounds write in the query processing components in Amazon Athena ODBC driver before 2.1.0.0 might allow a threat actor to crash the driver by using specially crafted data that is processed by the driver during query operations. To remediate this issue, users should upgrade to version 2.1.0.0. | ||||
| CVE-2016-20050 | 2 Foundstone, Mcafee | 2 Netschedscan, Netschedscan | 2026-04-15 | 6.2 Medium |
| NetSchedScan 1.0 contains a buffer overflow vulnerability in the scan Hostname/IP field that allows local attackers to crash the application by supplying an oversized input string. Attackers can paste a crafted payload containing 388 bytes of data followed by 4 bytes of EIP overwrite into the Hostname/IP field to trigger a denial of service condition. | ||||
| CVE-2026-33816 | 2 Jackc, Pgx Project | 2 Pgx, Pgx | 2026-04-15 | 9.8 Critical |

| CVE-2026-30814 | 1 Tp-link | 3 Archer Ax53, Archer Ax53 Firmware, Ax53 V1 | 2026-04-15 | 8.0 High |
| A stack-based buffer overflow in the tmpServer module of TP-Link Archer AX53 v1.0 allows an authenticated adjacent attacker to trigger a segmentation fault and potentially execute arbitrary code via a specially crafted configuration file. Successful exploitation may cause a crash and could allow arbitrary code execution, enabling modification of device state, exposure of sensitive data, or further compromise of device integrity. This issue affects AX53 v1.0: before 1.7.1 Build 20260213. | ||||
| CVE-2026-5443 | 2 Orthanc, Orthanc-server | 2 Dicom Server, Orthanc | 2026-04-15 | 9.8 Critical |
| A heap buffer overflow vulnerability exists during the decoding of `PALETTE COLOR` DICOM images. Pixel length validation uses 32-bit multiplication for width and height calculations. If these values overflow, the validation check incorrectly succeeds, allowing the decoder to read and write to memory beyond allocated buffers. | ||||
| CVE-2026-4152 | 1 Gimp | 1 Gimp | 2026-04-15 | 7.8 High |
| GIMP JP2 File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of JP2 files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28863. | ||||
| CVE-2026-4153 | 1 Gimp | 1 Gimp | 2026-04-15 | 7.8 High |
| GIMP PSP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GIMP. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PSP files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28874. | ||||
| CVE-2019-25695 | 1 R-project | 1 R | 2026-04-15 | 8.4 High |
