| A weakness has been identified in D-Link DSM-G600 1.01. This affects an unknown function of the file /load_file.cgi of the component Multipart Handler. Executing a manipulation can lead to out-of-bounds write. The attack may be launched remotely. The exploit has been made available to the public and could be used for attacks. |
| The GETALL and SETALL commands in semctl(2) recorded the number of semaphores in the target set, dropped the lock protecting the set, allocated a buffer sized for that count, and reacquired the lock. A sequence-number check was used to verify that the set had not been replaced in the interim, but the sequence number wraps after 0x8000 create/destroy cycles. By rapidly destroying and recreating semaphore sets at the same index, another process can cause the sequence number to wrap, allowing a set with a different number of semaphores to pass validation. The subsequent copy then reads or writes past the end of the allocated buffer.
An unprivileged local user can trigger out-of-bounds reads and writes on kernel heap memory, potentially leading to privilege escalation. |
| The ELF core dump code counted the number of dumpable VM map entries, allocated a buffer for the corresponding program headers, then iterated over the map a second time to populate them. A process sharing the address space via rfork(2) can mutate the map between the two passes, causing the second pass to write program headers past the end of the buffer.
An unprivileged local user sharing an address space with a process that dumps core can trigger an out-of-bounds write on the kernel heap, potentially leading to privilege escalation. |
| In the Linux kernel, the following vulnerability has been resolved:
octeontx2-af: npc: Fix size of entry2cntr_map
KASAN prints below splat. This is caused by allocating counter for
reserved mcam entry for cpt 2nd pass entry. But mcam->entry2cntr_map
is not allocated for reserved entries.

| A vulnerability was identified in diem-project diem up to 5.1.3. The affected element is the function executeCommand of the file dmAdminPlugin/modules/dmConsole/actions/actions.class.php of the component Administrative Console. Such manipulation of the argument dm_command leads to os command injection. The attack can be launched remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet. |
| Dell PowerStore SDNAS, contains an Out-of-bounds Write vulnerability in SMB/CIFS. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to denial of service and remote execution. This is a Critical vulnerability as a remote user could send a specially crafted SMB packet and cause a crash, that is persistent in case automatic restarts are enabled. Additionally, a more sophisticated attacker could use the same vulnerability for remote code execution. |
| In the Linux kernel, the following vulnerability has been resolved:
net: lwtunnel: Drop skb metadata before LWT encapsulation
skb metadata is meant for passing information between XDP and TC. It lives
in the skb headroom, immediately before skb->data. LWT programs cannot
access the __sk_buff->data_meta pseudo-pointer to metadata.
However, LWT encapsulation prepends outer headers, moving skb->data back
over the headroom where the metadata sits. On an RX-originated (forwarded)
packet that still carries XDP metadata this goes wrong in two different
ways, depending on the encap type:
1. Non-BPF LWT encaps (mpls, seg6, ioam6 ...) call skb_push()/skb_pull()
and silently overwrite the metadata that sits in the headroom.
2) BPF LWT xmit calls bpf_skb_change_head(), which uses skb_data_move().
That helper expects metadata immediately before skb->data. But since
the IP output path runs LWT xmit before neighbour output has built
the outgoing L2 header, for forwarded packets skb->data points at the
L3 header while skb_mac_header() still points at the old L2 header.
skb_data_move() sees metadata ending at skb_mac_header(), not before
skb->data, warns and clears metadata:

That is what happens, as for how to fix it - a received packet that
carries metadata can reach an encap through any of the three LWT
redirect modes:
LWTUNNEL_STATE_INPUT_REDIRECT
ip6_rcv_finish
dst_input
lwtunnel_input
LWTUNNEL_STATE_OUTPUT_REDIRECT
ip6_rcv_finish
dst_input
ip6_forward
ip6_forward_finish
dst_output
lwtunnel_output
LWTUNNEL_STATE_XMIT_REDIRECT
ip6_rcv_finish
dst_input
ip6_forward
ip6_forward_finish
dst_output
ip6_output
ip6_finish_output
ip6_finish_output2
lwtunnel_xmit
Every encap funnels through the three LWT dispatch helpers, so drop the
metadata there, right before handing the skb to the encap op. This
single chokepoint covers all encap types and all three redirect modes:
- lwtunnel_input(): seg6, rpl, ila, seg6_local
- lwtunnel_output(): ioam6
- lwtunnel_xmit(): mpls, LWT BPF xmit
Alternatively, we could clear the metadata right after TC ingress hook.
That would require a compromise, however. Metadata would become
inaccessible from TC egress (in setups where it actually reaches the
hook it tact, that is without any L2 tunnels on path). |
| In the Linux kernel, the following vulnerability has been resolved:
net: airoha: fix foe_check_time allocation size
foe_check_time is declared as u16 pointer but was allocated with
only ppe_num_entries bytes instead of ppe_num_entries * sizeof(u16).
When airoha_ppe_foe_verify_entry() is called with hash >= ppe_num_entries/2,
it writes beyond the allocated buffer, causing heap buffer overflow and
potential kernel crash. |
| A buffer overflow vulnerability in the WatchGuard Fireware OS Management Web UI allows an authenticated administrator with network access to cause a denial of service (DoS) condition or potentially execute arbitrary code by sending specially crafted network traffic. |
| OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. Versions 3.3.0 through 3.3.12 and 3.4.0 through 3.4.13 contain a heap buffer overflow in PyOpenEXR triggered by a channel-name key collision between literal and prefixed RGB channels. When separate_channels=false, PyOpenEXR maps each physical channel name through channelNameToRGBA() and coalesces the results into a shared RGB array. A crafted flat scanline EXR that contains both a literal channel such as left and prefixed channels such as left.R, left.G, and left.B causes these names to collide, so the wrapper reuses an undersized two-dimensional NumPy array for the coalesced RGB slices and writes out of bounds when OpenEXR.File(path) decodes the pixels. This issue is fixed in versions 3.3.13 and 3.4.14. |
| mcp-shell is an MCP server for running shell commands securely, auditably, and on demand. Prior to 0.6.0, the default security.yaml allows /usr/bin/git, while security.go omits ! from containsShellMetacharacters and containsDangerousShellConstructs and applies no per-executable argument policy. A caller of the shell_exec MCP tool can provide the command argument /usr/bin/git -c alias.pwn=!<arbitrary-command>, causing Git to create a shell alias and execute arbitrary OS commands as the mcp-shell process user. The default Docker image runs as mcpuser with Git installed and secure mode enabled, so the bypass is exploitable in the default deployment without additional authentication beyond MCP connectivity. This issue is fixed in version 0.6.0. |
| The Okta Privileged Access client does not reject a leading hyphen in the username portion of an SSH target. As a result, the value may be interpreted as a command-line option by the underlying SSH process. |
| SMM IHISI command handler, FMTSWriteUseIntelLib, for FMTS command 0x32, read and write data without checking buffer size and could cause buffer overflow. |
| Dell PowerProtect One, versions 20.1.0.0 and below, contain an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Code execution. |
| CVE-2025-40843 https://github.com/advisories/GHSA-5xf2-f6ch-6p8r was fixed by replacing unchecked strcpy() with a bounded safe_strcpy() helper.
At ldlogger-tool-gcc.c:129 the destination passed to that helper is fullPath + 2, but the size
passed down is the full PATH_MAX. safe_strcpy() is strncpy(), which NUL-pads the
destination out to the whole n, so this site writes 4096 bytes into the 4094 that remain — a
2-byte stack overflow on every invocation, independent of the input path's length.
This issue affects CodeChecker: through 6.28.2. |
| A flaw was found in FFmpeg. The tdsc_load_cursor() function writes beyond
the bounds of a heap-allocated buffer when processing crafted TDSC cursor
data. A remote attacker could exploit this by supplying a specially crafted
video file, potentially leading to a denial of service or arbitrary code
execution. |
| Passing an effectively empty string to the `,ccs=` syntax extension of the mode argument in the `fopen` function in the GNU C Library version 2.45 or earlier may result in a heap buffer overflow when the mode string input to the function is attacker controlled.
This usage pattern is not seen in applications in common GNU/Linux distributions and applications that process user-supplied values for `ccs` should not pass them through without validation. |
| A stack-based buffer overflow in the epm (Endpoint Protection Manager) service used by the deprecated Mobile Security feature in WatchGuard Fireware OS allows an unauthenticated remote attacker to execute arbitrary code. |
| Dell PowerProtect One, versions 20.1.0.0 and below, contain an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to Remote execution. |
