| CVE-2026-97423 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: cxl/region: Validate partition index before array access construct_region() reads cxled->part and uses it to index cxlds->part[] without checking for a negative value. If the partition was never resolved, part remains at its initial value of -1, causing an out-of-bounds array access. Add a guard to return -EBUSY when part is negative. The check was dropped during a merge. | ||||

| CVE-2026-77219 | 1 Gnu | 1 Emacs | 2026-10-01 | 7.1 High |
| GNU Emacs before 31.0.91 contains an integer overflow in the PBM/PPM/PGM image loader that allows an attacker to leak heap memory contents by supplying a crafted image with large dimensions and an elevated max color index. The image loader multiplies image dimensions and channel count using signed integer arithmetic; for sufficiently large values, the result wraps to a negative number, bypassing the bounds check and causing the pixel reader to access heap memory past the end of the allocated buffer. The over-read contents are interpreted as pixel color values and rendered on screen. | ||||
| CVE-2026-76641 | 2 Libexpat, Libexpat Project | 2 Expat, Libexpat | 2026-10-01 | 7.5 High |
| Expat through 2.8.3 contains an out-of-bounds read vulnerability that allows attackers to trigger memory corruption by processing XML with external entity parsers created via XML_ExternalEntityParserCreate. A struct size mismatch between ELEMENT_TYPE members causes storeAtts to read the attIndex member past allocated memory boundaries, resulting in failure to normalize whitespace in non-CDATA attributes or a wild pointer dereference causing a segfault. This vulnerability was introduced by the fix for CVE-2026-66046. | ||||
| CVE-2020-37165 | 2 Celestial Software, Celestialsoftware | 2 Absolutetelnet, Absolutetelnet | 2026-10-01 | 6.2 Medium |
| AbsoluteTelnet 11.12 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an oversized license name. Attackers can generate a 2500-character payload and paste it into the license name field to trigger an application crash. | ||||
| CVE-2020-37164 | 2 Celestial Software, Celestialsoftware | 2 Absolutetelnet, Absolutetelnet | 2026-10-01 | 6.2 Medium |
| AbsoluteTelnet 11.12 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an oversized license name. Attackers can generate a 2500-character payload and paste it into the license entry field to trigger an application crash. | ||||

| CVE-2026-97511 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: avoid out-of-bounds access in monitor In NAN, we don't know on what band the frame will be sent. Therefore we set info->band to NUM_NL80211_BANDS. However, this leads to out-of-bound access in ieee80211_add_tx_radiotap_header when we try to access the sbands array. Fix it by not accessing the array if the band is NUM_NL80211_BANDS. This means that we will not report rate info for legacy rate in NAN. But nobody really cares about it. | ||||
| CVE-2026-97551 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: xfs: initialise args->total for parent pointer updates xfs_parent_da_args_init() builds an xfs_da_args from a zeroed xfs_parent_args (kmem_cache_zalloc), leaving args->total == 0. xfs_da_grow_inode_int() treats that field as a running block reservation and subtracts from it; because it is an xfs_extlen_t (uint32_t), the first attr-fork growth wraps it to ~0U. That defeats the free-space check in xfs_alloc_space_available(), and when it coincides with an AG that has exactly zero available blocks the allocation is clamped to maxlen 0 and returns -ENOSPC, which xfs_defer_finish_noroll() escalates to a filesystem shutdown. Set args->total the way the log recovery path does (xfs_attri_recover_work(), xfs_attr_item.c:706), in the add and replace paths that can grow the fork. Removals and lookups never grow it, so they leave the field alone, matching that switch. | ||||
| CVE-2026-97563 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: reject out-of-bounds DataOffset in CIFSSMBRead() The SMB1 synchronous read helper CIFSSMBRead() validates the server's DataLength against CIFSMaxBufSize and the caller's count, but never validates DataOffset. The copy source is formed as &pSMBr->hdr.Protocol + le16_to_cpu(pSMBr->DataOffset) and memcpy()'d for DataLength bytes with no check that the [DataOffset, DataOffset + DataLength) range lies within the response actually received from the server. A malicious or compromised SMB1 server can return a response carrying an in-range DataLength and a large DataOffset, driving the source pointer past the end of the response buffer. The memcpy() then copies adjacent kernel heap into the caller's read buffer (information disclosure), or reads unmapped memory and oopses (denial of service). SMB1 is not negotiated by default; reaching this code requires an explicit vers=1.0 mount. Both DataOffset and the received response length recorded in rsp_iov.iov_len are relative to the start of the SMB header, so reject the response unless DataOffset + DataLength fits within that length, using overflow-safe arithmetic, before forming the source pointer. The response length has been validated by the previous patch, so the DataOffset and DataLength fields can be read safely here. While here, make data_length unsigned. It holds a length derived from unsigned on-the-wire fields and is only ever compared against unsigned quantities; print it with %u accordingly, and add __func__ to the cifs_dbg() calls in this function. | ||||
| CVE-2026-97565 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: reject short READ responses in CIFSSMBRead() CIFSSMBRead() reads DataLengthHigh, DataLength and DataOffset out of the READ_RSP returned by the server without first checking that a whole READ_RSP was actually received. The length of the response is recorded in rsp_iov.iov_len, but nothing constrains it to be at least read_rsp_size before those fields are dereferenced. A malicious or compromised SMB1 server can return a response shorter than the READ_RSP header, so that parsing the header itself reads past the end of the receive buffer. SMB1 is not negotiated by default; reaching this code requires an explicit vers=1.0 mount. Reject the response unless it is at least read_rsp_size bytes long. | ||||
| CVE-2026-97621 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/rockchip: analogix_dp: fix unchecked bound endpoint name length rockchip_dp_drm_encoder_enable() uses sprintf() to format a device tree path into a 32-byte stack buffer. Device tree paths are not limited to this size, so a sufficiently long path can overflow the buffer. Use snprintf() with the destination size to truncate the generated name and keep the writes within bounds. | ||||
| CVE-2026-97913 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: accel: ethosu: Ensure cmd stream ends with a stop op While the QSIZE register setting should prevent an out of bounds access of the command stream, it is not clear whether the h/w generates an interrupt in this case as is required (to prevent a timeout). As a stop op is expected end of the command stream, let's just ensure it is present. A stop op in the middle of the command stream also makes no sense. | ||||
| CVE-2026-98045 | 1 Linux | 1 Linux Kernel | 2026-10-01 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Mark faultable stack helpers as sleepable The faultable variants of bpf_get_stack() and bpf_get_task_stack() pass may_fault=true into the common stack collection code. Resolving user-space build IDs may then call build_id_parse_file() and block on filesystem reads. Neither helper prototype sets might_sleep. Since prototype selection uses the sleepability of the whole program, the verifier can still allow these helpers from a non-sleepable region within that program, such as an explicit RCU or preemption-disabled region. The task-stack helper can also be called from a non-sleepable timer callback of a sleepable program. Mark both faultable prototypes as sleepable. The existing helper context check then rejects these calls while continuing to allow them in genuinely sleepable contexts. | ||||
| CVE-2026-94952 | 1 Totolink | 1 N150rt | 2026-10-01 | 9.8 Critical |
| A stack-based buffer overflow vulnerability exists in the web management interface of TOTOLINK N150RT (NTR150) firmware V3.4.0-B20201030. It is reachable through the route /boafrm/formPortFw (port-forwarding configuration handler) and is triggered by the ip_subnet and fw_ip request parameters during the rule-addition flow. | ||||
