CVSS v3.1 |
| In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP bcmath extension functions on some systems, including Windows, can be tricked into reading beyond the allocated space by supplying it with string containing characters that are identified as numeric by the OS but aren't ASCII numbers. This can read to disclosure of the content of some memory locations. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/rxe: Copy WQE to local buffer in non-SRQ receive path
For non-SRQ QPs, the responder reads WQE fields directly from the
shared queue buffer mapped into userspace. This allows a malicious
user to modify fields like num_sge or sge entries while the kernel
is processing the WQE, leading to out-of-bounds reads in
rxe_resp_check_length() and copy_data().
Introduce get_recv_wqe() that validates num_sge and copies the WQE
to a kernel-local buffer before processing, matching the approach
already used for SRQ WQEs in get_srq_wqe(). The srq_wqe buffer is
reused since SRQ and non-SRQ paths are mutually exclusive per QP. |
| Red Hat CNA-LR concluded that this CVE is not valid. |
| In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Don't move a peeked OOB message onto the pending queue
rxrpc_recvmsg_oob() takes a received oob message off recvmsg_oobq and,
if a response is needed, moves it onto the pending_oobq tree. However,
only the unlink from recvmsg_oobq is guarded by MSG_PEEK; the move onto
pending_oobq always runs.
As a result, reading a challenge with MSG_PEEK leaves the skb on
recvmsg_oobq while also adding it to pending_oobq. Since struct
sk_buff's rbnode shares storage with its next and prev pointers,
rb_insert_color() overwrites the list linkage, and the skb, which holds
a single reference, becomes reachable from both queues at once.
When the socket is closed both queues are drained in turn. While
draining recvmsg_oobq, __skb_unlink() follows the next and prev
pointers that rbnode has overwritten and writes to a bad address. Also,
as the skb holds a single reference but is freed from each queue, both
the skb and the connection reference it holds are released twice. This
leads to memory corruption and to a use-after-free caused by the
connection refcount underflow.
MSG_PEEK does not consume the message from the queue, so only unlink it
from recvmsg_oobq and then move it onto pending_oobq or free it when
the message is actually consumed. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: wcn36xx: fix heap overflow from oversized firmware HAL response
The firmware response dispatcher copies all synchronous HAL responses
into the 4096-byte hal_buf without validating the response length. A
response exceeding WCN36XX_HAL_BUF_SIZE causes a heap buffer overflow
with firmware-controlled content.
Add a bounds check on the response length. |
| In the Linux kernel, the following vulnerability has been resolved:
afs: handle CB.InitCallBackState3 requests without a server record
The cache manager callback path now attaches the server record to an
incoming call through the rxrpc peer's app data. That association is
not guaranteed to exist for every callback request, and most callback
handlers already tolerate that case.
Make CB.InitCallBackState3 follow the same pattern by checking whether a
server record was attached before using it. If the peer is not mapped
to a server record, trace the request and ignore it, matching the
existing behaviour for other unmatched callback requests.
This keeps the callback handler consistent with the rest of the cache
manager service and avoids depending on peer state that may not be
available for a given request. |
| IBM Documentation Offline 1.0.0 through 1.4.1 could allow a remote attacker to execute arbitrary code due to improper output neutralization for logs. |
| In Eclipse Theia versions up to and including 1.69.0, opening a folder starts source control integration without requiring the user to trust the folder first. This affects applications built on Theia that include the git integration, such as the Theia IDE. Both Theia's own `@theia/git` extension and the builtin VS Code `git` extension run git commands such as `git status` as soon as a repository is detected. Since git honors repository-local configuration, a folder containing an attacker-controlled `.git/config` with `core.fsmonitor` (or a comparable hook-like setting) causes the configured command to be executed. The configuration can be delivered by burying a bare repository inside a regular repository (OVE-20210718-0001), so cloning an attacker-supplied repository and opening it in a Theia-based application is sufficient to execute arbitrary commands with the privileges of the user, without any confirmation prompt.
As of 1.70.0, plugins that declare `capabilities.untrustedWorkspaces.supported: false`, which includes the builtin git extension, are no longer loaded or activated in an untrusted workspace, and the deprecated `@theia/git` extension has been removed, so no git command is executed against an untrusted folder. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: amd: acp-sdw-legacy: Bound DAI link iteration
create_sdw_dailinks() walks soc_dais until it finds an entry with
initialised cleared, but soc_dais is allocated with exactly num_ends
entries. If all entries are initialised, the loop reads past the end of
the array.
This was reported by KASAN:
BUG: KASAN: slab-out-of-bounds in mc_probe+0x26b3/0x2774 [snd_acp_sdw_legacy_mach]
Read of size 1
Pass the allocated entry count to create_sdw_dailinks() and stop before
reading past the array. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/panthor: reject firmware sections with oversized data
In panthor_fw_load_section_entry(), the data size to copy is calculated
without validating it against the allocated section_size:
section->data.size = hdr.data.end - hdr.data.start;
If a crafted firmware sets data.size larger than the allocated memory,
this could cause a heap buffer overflow in panthor_fw_init_section_mem()
memcpy(section->mem->kmap, section->data.buf, section->data.size);
Additionally, if the section->data.size exceeds the BO size, could this
memset underflow the size calculation, leading to a massive out-of-bounds
zeroing of kernel memory?
memset(section->mem->kmap + section->data.size, 0,
panthor_kernel_bo_size(section->mem) - section->data.size);
Reject section entries whose initial data is larger than the section size. |
| A flaw was found in SSSD. The extract_authtok_v1() function in the PAM responder does not validate the auth_token_length field against the remaining buffer size before processing. A local attacker can exploit this via a crafted protocol v1 request to the PAM responder socket, causing an out-of-bounds read and process crash, resulting in a denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs: harden runlist realloc size calculations
Add a shared helper to safely convert runlist element counts to byte sizes
using overflow checks, and use it in both ntfs_rl_realloc() and
ntfs_rl_realloc_nofail(). |
| In the Linux kernel, the following vulnerability has been resolved:
iommu/arm-smmu-v3-iommufd: Require exactly one Stream ID for a vDEVICE
arm_vsmmu_vsid_to_sid() maps a guest's vSID to a single physical Stream ID
taken from master->streams[0], assuming a device has exactly one stream. A
device with several streams gets only its first one mapped, so a guest vSID
invalidation cannot reach the others' ATC and IOTLB entries; a device with
none makes master->streams a ZERO_SIZE_PTR, read out of bounds.
Add an arm_vsmmu_vdevice_init() op to reject the vDEVICE with -EOPNOTSUPP
when master->num_streams is not one, rather than mapping it silently. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: amd: acp-sdw-sof: Bound DAI link iteration
create_sdw_dailinks() walks sof_dais until it finds an entry with
initialised cleared, but sof_dais is allocated with exactly num_ends
entries. If all entries are initialised, the loop reads past the end of
the array.
Pass the allocated entry count to create_sdw_dailinks() and stop before
reading past the array. |
| Hardware logic contains race conditions for some 3rd Gen Intel(R) Xeon(R) Scalable Processors within Ring 3: unprivileged software may allow a denial of service. Unprivileged software adversary with an authenticated user combined with a high complexity attack may enable denial of service. This result may potentially occur via local access when attack requirements are not present with special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (high) impacts. |
| Browserslist is a configuration tool for sharing target browsers and Node.js versions between front-end tools. Prior to 4.28.7, normalizeStats() in node.js, reached unconditionally through getStat() and loadStat() on every browserslist() call, processes untrusted browserslist-stats.json, opts.stats, and CLI --stats data with an unguarded for...in loop and plain-object bracket access and assignment, allowing inherited Object.prototype keys including __proto__, toString, valueOf, constructor, hasOwnProperty, and isPrototypeOf to cause an uncaught TypeError or modify the prototype of the returned normalized object. This issue is fixed in version 4.28.7. |
