CVE-2026-74682 is an out-of-bounds write in the Linux kernel ALSA usb-audio subsystem affecting Type II capture (inbound) URBs . In data_ep_set_params(), the URB transfer buffer size is computed before the Type II transfer delimiter packet is added to the packet count, leaving the buffer one pack...

CVE-2026-74669

CVE-2026-74669 is a stack out-of-bounds write in the Linux kernel's IPVS (IP Virtual Server) subsystem. The root cause lies in ip_vs_in_icmp(), which rebases a socket buffer from the outer ICMP packet to the quoted original request before calling icmp_send(). However, the IPCB(skb)->opt field ...

CVE-2026-74670

CVE-2026-74670 is an out-of-bounds write vulnerability in the Linux kernel IPVS (IP Virtual Server) subsystem. The IPVS estimator kthread starts with zeroed chain and tick limits until its initial calculation phase completes. If network namespace teardown clears ipvs->enable during that phase,...

CVE-2026-74649

CVE-2026-74649 affects the Linux kernel staging driver rtl8723bs . The WEP shared-key authentication handler in OnAuthClient() copies the challenge-text element into a fixed 128-byte chg_txt buffer using an attacker-controlled length (up to 255 bytes) without validation. A malicious AP can send a...

CVE-2026-74640

CVE-2026-74640 is an out-of-bounds write in the Linux kernel's ALSA FCP driver, specifically in fcp_meter_ctl_get(). The driver accepts a Level Meter map size up to 255 , but the kernel's snd_ctl_elem_value integer array is only 128 elements long. The store loop writes one 64-bit word per channel...

EUVD-2026-64312

hashcat's fgetl function in src/filehandling.c writes a null terminator one byte past the caller's buffer when an input line is exactly the buffer length. Attackers can trigger this out-of-bounds heap write by providing a hash file, potfile, or wordlist containing a line of exactly HCBUFSIZLARGE...

EUVD-2026-64313

hashcat contains a heap-based buffer overflow out-of-bounds write in the outfilewrite function in src/outfile.c. When assembling output into a fixed-size buffer HCBUFSIZLARGE, 16 MB, the function sequentially appends the username, separator, hash, and plaintext via memcpy without validating that...

CVE-2026-50538

LibVNCClient (part of the LibVNCServer project) versions 0.9.12 through 0.9.15 contain an out-of-bounds heap write in the Tight decoder . A malicious or man-in-the-middle VNC server can trigger this by sending a single crafted FramebufferUpdate message, writing attacker-controlled data past the e...

CVE-2026-77236

Missing minimum size validation in secure context allocation in FreeRTOS-Kernel before 11.3.1 might allow local users to corrupt secure-world heap metadata via an out-of-bounds write with an undersized stack size parameter. To remediate this issue, users should upgrade to version 11.3.1 or later...

CVE-2026-74582

A flaw was found in the Linux kernel's packet handling functions, specifically packetsnd and packetsendmsgspkt. This vulnerability arises from inconsistent handling of network device header lengths during packet construction. A local attacker could exploit this by triggering a race condition duri...

CVE-2026-77236 Missing size validation in SecureContext_AllocateContext in FreeRTOS-Kernel

Missing minimum size validation in secure context allocation in FreeRTOS-Kernel before 11.3.1 might allow local users to corrupt secure-world heap metadata via an out-of-bounds write with an undersized stack size parameter. To remediate this issue, users should upgrade to version 11.3.1 or later...

CVE-2026-77236 Missing size validation in SecureContext_AllocateContext in FreeRTOS-Kernel

Missing minimum size validation in secure context allocation in FreeRTOS-Kernel before 11.3.1 might allow local users to corrupt secure-world heap metadata via an out-of-bounds write with an undersized stack size parameter.

To remediate this issue, users should upgrade to version 11.3.1 or later...

CVE-2026-77236

CVE-2026-77236 is a missing input validation vulnerability in the SecureContext_AllocateContext function of FreeRTOS-Kernel prior to version 11.3.1. The absence of a minimum size check on the stack size parameter allows a local attacker to trigger an out-of-bounds write that corrupts secure-world...

CVE-2026-17252

A stack-based out-of-bounds write vulnerability exists in the login request handling of the administrative web interface on TP-Link TL-MR6400 v7 routers.
