Vulnerabilidades

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> Bluetooth: L2CAP: Validate L2CAP_INFO_RSP payload length before access<br /> <br /> l2cap_information_rsp() checks that cmd_len covers the fixed<br /> l2cap_info_rsp header (type + result, 4 bytes) but then reads<br /> rsp-&gt;data without verifying that the payload is present:<br /> <br /> - L2CAP_IT_FEAT_MASK calls get_unaligned_le32(rsp-&gt;data), which reads<br /> 4 bytes past the header (needs cmd_len &gt;= 8).<br /> <br /> - L2CAP_IT_FIXED_CHAN reads rsp-&gt;data[0], 1 byte past the header<br /> (needs cmd_len &gt;= 5).<br /> <br /> A truncated L2CAP_INFO_RSP with result == L2CAP_IR_SUCCESS triggers an<br /> out-of-bounds read of adjacent skb data.<br /> <br /> Guard each data access with the required payload length check. If the<br /> payload is too short, skip the read and let the state machine complete<br /> with safe defaults (feat_mask and remote_fixed_chan remain zero from<br /> kzalloc), so the info timer cleanup and l2cap_conn_start() still run<br /> and the connection is not stalled.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> bnxt_en: fix OOB access in DBG_BUF_PRODUCER async event handler<br /> <br /> The ASYNC_EVENT_CMPL_EVENT_ID_DBG_BUF_PRODUCER handler in<br /> bnxt_async_event_process() uses a firmware-supplied &amp;#39;type&amp;#39; field<br /> directly as an index into bp-&gt;bs_trace[] without bounds validation.<br /> <br /> The &amp;#39;type&amp;#39; field is a 16-bit value extracted from DMA-mapped completion<br /> ring memory that the NIC writes directly to host RAM. A malicious or<br /> compromised NIC can supply any value from 0 to 65535, causing an<br /> out-of-bounds access into kernel heap memory.<br /> <br /> The bnxt_bs_trace_check_wrap() call then dereferences bs_trace-&gt;magic_byte<br /> and writes to bs_trace-&gt;last_offset and bs_trace-&gt;wrapped, leading to<br /> kernel memory corruption or a crash.<br /> <br /> Fix by adding a bounds check and defining BNXT_TRACE_MAX as<br /> DBG_LOG_BUFFER_FLUSH_REQ_TYPE_ERR_QPC_TRACE + 1 to cover all currently<br /> defined firmware trace types (0x0 through 0xc).

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mac80211: fix crash in ieee80211_chan_bw_change for AP_VLAN stations<br /> <br /> ieee80211_chan_bw_change() iterates all stations and accesses<br /> link-&gt;reserved.oper via sta-&gt;sdata-&gt;link[link_id]. For stations on<br /> AP_VLAN interfaces (e.g. 4addr WDS clients), sta-&gt;sdata points to<br /> the VLAN sdata, whose link never participates in chanctx reservations.<br /> This leaves link-&gt;reserved.oper zero-initialized with chan == NULL,<br /> causing a NULL pointer dereference in __ieee80211_sta_cap_rx_bw()<br /> when accessing chandef-&gt;chan-&gt;band during CSA.<br /> <br /> Resolve the VLAN sdata to its parent AP sdata using get_bss_sdata()<br /> before accessing link data.<br /> <br /> [also change sta-&gt;sdata in ARRAY_SIZE even if it doesn&amp;#39;t matter]

*** Pendiente de traducción *** immich is a high performance self-hosted photo and video management solution. Prior to version 2.6.0, the Immich application is vulnerable to credential disclosure when a user authenticates to a shared album. During the authentication process, the application transmits the album password within the URL query parameters in a GET request to /api/shared-links/me. This exposes the password in browser history, proxy and server logs, and referrer headers, allowing unintended disclosure of authentication credentials. The impact of this vulnerability is the potential compromise of shared album access and unauthorized exposure of sensitive user data. This issue has been patched in version 2.6.0.

*** Pendiente de traducción *** FastMCP is the standard framework for building MCP applications. Prior to version 3.2.0, while testing the GitHubProvider OAuth integration, which allows authentication to a FastMCP MCP server via a FastMCP OAuthProxy using GitHub OAuth, it was discovered that the FastMCP OAuthProxy does not properly validate the user&amp;#39;s consent upon receiving the authorization code from GitHub. In combination with GitHub’s behavior of skipping the consent page for previously authorized clients, this introduces a Confused Deputy vulnerability. This issue has been patched in version 3.2.0.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> spi: fix use-after-free on controller registration failure<br /> <br /> Make sure to deregister from driver core also in the unlikely event that<br /> per-cpu statistics allocation fails during controller registration to<br /> avoid use-after-free (of driver resources) and unclocked register<br /> accesses.

*** Pendiente de traducción *** Budibase is an open-source low-code platform. Prior to version 3.33.4, the bash automation step executes user-provided commands using execSync without proper sanitization or validation. User input is processed through processStringSync which allows template interpolation, potentially allowing arbitrary command execution. This issue has been patched in version 3.33.4.

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> mtd: Avoid boot crash in RedBoot partition table parser<br /> <br /> Given CONFIG_FORTIFY_SOURCE=y and a recent compiler,<br /> commit 439a1bcac648 ("fortify: Use __builtin_dynamic_object_size() when<br /> available") produces the warning below and an oops.<br /> <br /> Searching for RedBoot partition table in 50000000.flash at offset 0x7e0000<br /> ------------[ cut here ]------------<br /> WARNING: lib/string_helpers.c:1035 at 0xc029e04c, CPU#0: swapper/0/1<br /> memcmp: detected buffer overflow: 15 byte read of buffer size 14<br /> Modules linked in:<br /> CPU: 0 UID: 0 PID: 1 Comm: swapper/0 Not tainted 6.19.0 #1 NONE<br /> <br /> As Kees said, "&amp;#39;names&amp;#39; is pointing to the final &amp;#39;namelen&amp;#39; many bytes<br /> of the allocation ... &amp;#39;namelen&amp;#39; could be basically any length at all.<br /> This fortify warning looks legit to me -- this code used to be reading<br /> beyond the end of the allocation."<br /> <br /> Since the size of the dynamic allocation is calculated with strlen()<br /> we can use strcmp() instead of memcmp() and remain within bounds.

*** Pendiente de traducción *** Budibase is an open-source low-code platform. Prior to version 3.23.25, a business logic vulnerability exists in Budibase’s password reset functionality due to the absence of rate limiting, CAPTCHA, or abuse prevention mechanisms on the “Forgot Password” endpoint. An unauthenticated attacker can repeatedly trigger password reset requests for the same email address, resulting in hundreds of password reset emails being sent in a short time window. This enables large-scale email flooding, user harassment, denial of service (DoS) against user inboxes, and potential financial and reputational impact for Budibase. This issue has been patched in version 3.23.25.
