wifi: rtw89: Correct data type for scan index to avoid infinite loop
A kernel soft lockup was observed during Wi-Fi scanning on the 6GHz band.
The CPU becomes stuck in rtw89_hw_scan_add_chan_ax for over 20 seconds,
leading to a system panic.
RIP points to 0f b6 c3 (movzbl %bl, %eax), which zero-extends
the low 8 bits of RBX into RAX.
RBX (the counter i) has reached a huge value: 0x137466a1.

| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer
In rtw_pci_rx_napi(), new_len is computed as the sum of pkt_len (14-bit
descriptor field, max 16383) and pkt_offset (drv_info_sz + shift, both
firmware-controlled). The result can exceed RTK_PCI_RX_BUF_SIZE (11478),
causing an out-of-bounds read from the pre-allocated DMA buffer when
skb_put_data copies new_len bytes. The USB transport already validates
this (rtw_usb_rx_data_put checks against RTW_USB_MAX_RECVBUF_SZ); the
PCIe path does not.
Add a check that new_len does not exceed the DMA buffer size. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: add bounds check on firmware mac_id in link lookup
The mac_id field in RX descriptors is 8 bits wide (0-255), but
assoc_link_on_macid[] has only RTW89_MAX_MAC_ID_NUM (128) entries.
While the driver currently assigns mac_id values below 128, the
descriptor value comes from firmware and is not validated before use
as an array index. Add a defensive bounds check in
rtw89_assoc_link_rcu_dereference() to guard against out-of-range
firmware values. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath9k: fix OOB access from firmware tx status queue ID
ath_tx_edma_tasklet() accesses sc->tx.txq[ts.qid] where ts.qid is a
4-bit hardware field (0-15), but the txq array only has
ATH9K_NUM_TX_QUEUES (10) entries. A qid >= 10 causes an OOB array
access.
Add a bounds check on ts.qid before using it as an array index. |
| In the Linux kernel, the following vulnerability has been resolved:

Fix this by accounting for the entry about to be written to, in addition to
the entries that are already allocated. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: fix integer overflow in immediate data length check
imm_buf->len is a user-controlled uint32_t received from the network.
Adding it to imm_data_offset without overflow checking allows a
malicious initiator to send len=0xFFFFFFFF, causing req_size to wrap
around to a small value, bypassing the bounds check, and subsequently
passing a ~4GB length to sg_init_one().
Use check_add_overflow() to detect wrapping before the comparison. |
| ExtUtils::Typemaps::STL::List versions before 1.07 for Perl allocate a 32 GiB array on an empty list.
The OUTPUT typemaps call av_extend( av, len-1 ). On an empty list, this undeflows, and av_extend will allocate an array with 2^32 slots, leading to memory exhaustion.
Note that a similar issue was fixed in ExtUtils::Typemaps::STL::Vector version 1.05. |
| MP4v2 through 2.1.3 contains a heap-based out-of-bounds read in MP4File::GetChapters() that allows attackers to read past heap allocations via crafted QuickTime chapter samples. Attackers can supply an MP4 file whose chapter sample is shorter than its declared title length, crashing applications like mp4chaps or leaking adjacent heap memory into chapter titles. |
| An external control of system or configuration setting vulnerability has been reported to affect QuRouter. If a local attacker gains an administrator account, they can then exploit the vulnerability to modify data on the system.
We have already fixed the vulnerability in the following version:
QuRouter 2.7.2.113 and later |
| Improper Validation of Syntactic Correctness of Input vulnerability in mtrudel bandit allows an unauthenticated remote attacker to set conn.host and conn.port to values outside the RFC 3986 host grammar via the authority of an HTTP/1 absolute-form or authority-form request target. Bandit validates the Host header and answers 400 when it is malformed, but when the request target carries its own authority that authority takes precedence, as RFC 9112 requires, and Bandit.Pipeline.determine_host_and_port!/4 in lib/bandit/pipeline.ex passes it to the application unchecked. A request line such as GET http://good.example@evil.example/x HTTP/1.1 with a valid Host header yields a conn.host of good.example@evil.example, and the same path admits NUL, DEL and non-ASCII bytes, invalid IP literals and ports outside 1..65535. The HTTP/1.0 clause needs no Host header at all, and CONNECT places the unparsed port string in conn.port.
Applications that build absolute URLs from conn.host, such as through Plug.Conn.request_url/1 or Phoenix URL helpers, emit links whose authority the attacker chose. Message framing is unaffected, and no CR or LF can reach conn.host.
This issue affects bandit: from 0.6.0 before 1.13.0. |

| During Xenstore live update the state record for a Xenstore watch with
specified watch depth is written with two bytes missing. This results
in an inconsistent state when reading the state back in the new Xenstore,
causing a crash of Xenstore or wrong Xenstore data. |
| In the Linux kernel, the following vulnerability has been resolved:
gpu: host1x: Fix iommu_map_sgtable() return value check
Commit "iommu: return full error code from iommu_map_sg[_atomic]()"
changed iommu_map_sgtable() to return an ssize_t and negative values
in error cases, rather than a size_t and a zero.
pin_job() also was incorrectly assigning to 'int', which could cause
overflows into negative values.
Update pin_job() to correctly check for errors from iommu_map_sgtable. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Fix TOCTOU heap overflow in get_srq_wqe
get_srq_wqe() reads wqe->dma.num_sge from the shared receive queue
buffer, which is mapped into userspace. It validates num_sge against
max_sge, but then re-reads the same field to calculate the memcpy
size. A concurrent userspace thread can modify num_sge between
validation and use, causing a heap buffer overflow when copying the
WQE into qp->resp.srq_wqe.
Read num_sge into a local variable and use it for both the bounds
check and the size calculation. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix OOB read from firmware count in PRINT_REG_INFO indication
The firmware-controlled rsp->count field is used as the loop bound for
indexing into the flexible rsp->regs[] array without validation against
the message length. A count exceeding the actual data causes out-of-
bounds reads from the heap-allocated message buffer.
Add a check that count fits within the received message. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: meson: aiu: Validate written enum values
The AIU HDMI and internal codec mux put callbacks use the written enum
value with snd_soc_enum_item_to_val() before checking whether the value is
valid for the enumeration.
Reject out-of-range values before converting the enum item, matching the
validation already done by the G12A HDMI and internal codec mux controls. |
| In the Linux kernel, the following vulnerability has been resolved:
sctp: validate embedded address parameter length
sctp_verify_asconf() and sctp_verify_param() only validate ADD_IP, DEL_IP,
and SET_PRIMARY parameters against a fixed minimum size of sizeof(struct
sctp_addip_param) + sizeof(struct sctp_paramhdr). This ensures the outer
parameter is large enough to contain an embedded address parameter header,
but does not verify that the embedded address parameter's declared length
fits within the bounds of the outer parameter.
Later, sctp_process_param() and sctp_process_asconf_param() extract the
embedded address parameter and pass it to af->from_addr_param(), which uses
the address parameter length to parse the variable-length address payload.
A malformed peer can therefore advertise an embedded address parameter
length that exceeds the remaining bytes in the enclosing parameter.
Validate that addr_param->p.length does not exceed the space available
after the sctp_addip_param header before processing the embedded address
parameter. Reject malformed parameters when the embedded address length
extends beyond the enclosing parameter bounds.
This prevents out-of-bounds reads when parsing malformed parameters carried
in INIT or ASCONF processing paths. |
