| CVE-2026-51934 | 1 Tenda | 1 A18 | 2026-09-03 | 9.8 Critical |
| Buffer Overflow vulnerability in Shenzhen Jixiang Tengda Technology Co., Ltd. Tenda A18 v.15.13.07.09 allows a remote attacker to execute arbitrary code via the fromSetCmdlineRun function | ||||
| CVE-2026-64446 | 1 Linux | 1 Linux Kernel | 2026-09-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: fix heap buffer overflow in rtw_cfg80211_set_wpa_ie() supplicant_ie is a 256-byte array in struct security_priv. The WPA and WPA2 IE copy paths use: memcpy(padapter->securitypriv.supplicant_ie, &pwpa[0], wpa_ielen + 2); where wpa_ielen is the raw IE length field (u8, 0-255). When a local user supplies a connect request via nl80211 with a crafted WPA IE of length 255, wpa_ielen + 2 equals 257, overflowing the 256-byte buffer by one byte into the adjacent last_mic_err_time field. rtw_parse_wpa_ie() does not prevent this: its length consistency check compares *(wpa_ie+1) against (u8)(wpa_ie_len-2), which is (u8)(255) == 255 when wpa_ie_len = 257, so the check passes silently. Add explicit bounds checks for both the WPA and WPA2 paths before the memcpy, rejecting any IE whose total size (wpa_ielen + 2) exceeds the supplicant_ie buffer. | ||||

| CVE-2026-64085 | 1 Linux | 1 Linux Kernel | 2026-09-03 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: hwmon: (pmbus/adm1266) bounce blackbox records through a protocol-sized buffer adm1266_pmbus_block_xfer() copies the device-supplied block payload into the caller-provided buffer using the device-supplied length: memcpy(data_r, &msgs[1].buf[1], msgs[1].buf[0]); The helper does not know how large data_r is and trusts the device to return at most one record's worth of bytes. adm1266_nvmem_read_blackbox() violates that contract: it advances read_buff inside data->dev_mem in ADM1266_BLACKBOX_SIZE (64-byte) strides while the helper is willing to write up to ADM1266_PMBUS_BLOCK_MAX (255) bytes. A device that returns more than 64 bytes on the trailing record (read_buff offset 1984 in the 2048-byte dev_mem allocation) overflows dev_mem by up to 191 bytes before the post-call if (ret != ADM1266_BLACKBOX_SIZE) return -EIO; can reject the response. Contain the fix in the caller without changing the helper signature: read each record into a 255-byte local bounce buffer that matches the helper's maximum output, validate the returned length, and only then copy exactly ADM1266_BLACKBOX_SIZE bytes into the dev_mem slot. | ||||
| CVE-2026-18296 | 1 Gstreamer | 1 Gstreamer | 2026-09-02 | 7.8 High |

| CVE-2025-22104 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-09-02 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: ibmvnic: Use kernel helpers for hex dumps Previously, when the driver was printing hex dumps, the buffer was cast to an 8 byte long and printed using string formatters. If the buffer size was not a multiple of 8 then a read buffer overflow was possible. Therefore, create a new ibmvnic function that loops over a buffer and calls hex_dump_to_buffer instead.

| CVE-2026-75124 | 1 Planet Technology Corp | 1 Planet Gs-4210-16p2s | 2026-09-01 | 7.5 High |
| PLANET GS-4210-16P2S V3 firmware before 3.441b260626 contains a pre-authentication memory corruption vulnerability in the web management interface where the _readHttpParam function copies an oversized HTTP query string without guaranteeing NUL termination, allowing parse_query_string to process attacker-controlled data into a fixed-size stack buffer. An unauthenticated remote attacker can send an oversized GET request to dispatcher.cgi to cause denial of service of the web management interface and potentially trigger memory corruption. | ||||

| CVE-2026-82343 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-09-01 | 6.1 Medium |
| A flaw was found in the file-psd plugin in GIMP. When processing a specially crafted PSD image file, the plugin does not properly validate the channel-count parameter. This incorrect validation leads to improper memory bounds checking, resulting in both a heap out-of-bounds read and a stack out-of-bounds access. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of memory contents. | ||||
