CVE-2026-90052 1 Linux 1 Linux Kernel 2026-10-19 N/A
This CVE ID has been rejected or withdrawn by its CVE Numbering Authority.
CVE-2026-55246 1 Tatsh 1 Bincookie 2026-10-19 7.8 High
bincookie is a header-only binarycookies parser. Prior to 0.1.9, bincookie_init_file() in bincookie.h allocates a buffer using the actual .binarycookies file length but trusts the file-controlled num_pages field as the loop bound for byte-swapping page_sizes entries. A crafted file can make the loop read and write beyond the heap allocation, and related unvalidated page sizes and cookie_offsets can drive additional out-of-bounds accesses in page and cookie iteration. Applications that parse an attacker-supplied binarycookies file may crash or suffer heap corruption that can potentially enable code execution. This issue is fixed in version 0.1.9.
CVE-2026-98570 1 Linux 1 Linux Kernel 2026-10-19 5.9 Medium
In the Linux kernel, the following vulnerability has been resolved: net: ipv6: keep room for the mac header in dst_dev_overhead() The seg6, ioam6 and rpl lwtunnels size their skb_cow_head() request as the length they are about to push plus dst_dev_overhead(), then push the new headers and rebuild the mac header below them with skb_mac_header_rebuild(). That rebuild needs skb->mac_len of headroom, but dst_dev_overhead() leaves LL_RESERVED_SPACE() of the egress device, 16 bytes for plain Ethernet. Where the mac header is longer than that, as it is on ingress through a VLAN device with reorder_hdr off, the rebuild runs out of room: skb_set_mac_header(skb, -skb->mac_len) computes a negative offset, stores it unchecked in the u16 skb->mac_header, and the memmove that follows writes skb->mac_len bytes about 64 KB past skb->head. Forwarding plain ping6 traffic through such a device reproduces it on all five seg6 encapsulation modes and on the rpl and ioam6 inline paths; skb->mac_header comes back as 65534 on a 704-byte head. Return the larger of the two. The helper already returns skb->mac_len when it has no dst, so this only makes the other branch agree, and it covers every caller rather than each call site in turn.
CVE-2025-20731 2 Mediatek, Openwrt 10 Mt6890, Mt7615, Mt7622 and 7 more 2026-10-18 5.3 Medium
In wlan AP driver, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege (when OceReducedNeighborReport is disabled). User interaction is not needed for exploitation. Patch ID: WCNCR00441511; Issue ID: MSV-4140.
CVE-2026-97810 1 Microsoft 11 Windows 11 24h2, Windows 11 24h2, Windows 11 25h2 and 8 more 2026-10-18 7 High

CVE-2026-55893 1 Capstone-engine 1 Capstone 2026-10-18 7.0 High
Capstone is a disassembly framework. In 6.0.0-Alpha9 and earlier, Capstone's arch/SH/SHDisassembler.c SH floating-point decoders such as opFADD, opFMUL, and opFSUB call set_reg() and set_reg_n() using sh_info.op.op_count without checking the fixed-size operands[] array. Repeated crafted instructions processed through cs_disasm_iter() or cs_disasm() with CS_ARCH_SH, CS_MODE_SH2A or CS_MODE_SH4A, CS_MODE_SHFPU, and CS_OPT_DETAIL can increment the operand count beyond the 176-byte sh_info allocation and perform a four-byte heap buffer overflow write. The corruption can crash the process and may enable code execution depending on heap layout. This issue is fixed in version 6.0.0-Alpha10.
CVE-2026-97815 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-18 9.8 Critical

CVE-2026-93479 1 F5 2 Nginx Open Source, Nginx Plus 2026-10-18 8.1 High
A vulnerability exists in NGINX Plus and NGINX Open Source when a map directive uses regex matching and the root directive or access log format references the map's regex capture variables before referencing the map output variable. Alternatively, the same result could be achieved by using a non-cacheable variable in a string expression under certain conditions. An unauthenticated attacker along with conditions beyond their control can exploit this vulnerability by sending crafted HTTP requests. This may cause a heap buffer overflow in the NGINX worker process leading to a restart. Additionally, attackers can execute code on systems with Address Space Layout Randomization (ASLR) disabled or when the attacker can bypass ASLR. Impact:  This vulnerability may allow remote attackers to cause a denial-of-service (DoS) on the NGINX system or to possibly trigger a code execution. There is no control plane exposure; this is a data plane issue only. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

CVE-2026-87716 1 Microsoft 20 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 17 more 2026-10-18 7.5 High
Heap-based buffer overflow in Windows Storage Spaces Controller allows an unauthorized attacker to deny service over a network.
CVE-2026-78433 1 Gitea 1 Gitea 2026-10-18 5.9 Medium
Gitea's web attachment handler skips its cross-repository ownership check for attachments created before 16 January 2026 and checks permissions against the repository named in the request URL instead. An unauthenticated attacker who knows a private attachment's UUID can request it through a public repository's attachment path and retrieve its contents. This can expose issue and pull request attachments or release assets; the random attachment UUID must already be known to the attacker.
CVE-2026-111885 1 Phpmyfaq 1 Phpmyfaq 2026-10-18 5.5 Medium
phpMyFAQ from 4.2.0-alpha before 4.2.0-beta contains a missing authorization vulnerability in GroupController::deleteGroup() that omits privilege-level checks on target groups. Authenticated non-SuperAdmin administrators holding GROUP_DELETE can send a crafted groupId to /admin/api/group/delete to permanently destroy higher-privileged groups and strip members' inherited rights.
CVE-2026-85822 1 Microsoft 28 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 25 more 2026-10-18 7.8 High
