Android Wrapped Key Import Logic Error Enables Local Privilege Escalation

In multiple locations, there is a possible way to bypass key authorization policies during wrapped key import due to a logic error. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

inet: reject unhashed sockets during established lookups

In the Linux kernel, the following vulnerability has been resolved: inet: reject unhashed sockets during established lookups TCP established ehash lookups are lockless. The socket caches involved use SLAB_TYPESAFE_BY_RCU, so memory can be reused before an RCU reader that retained its old address has finished. After a tuple match, __inet_lookup_established() and __inet6_lookup_established() acquire a reference and repeat the tuple check. They do not check whether the new object is hashed. If the address is reused for a socket with the same tuple, the lookup can acquire a reference to the new object and return it while its nulls node is unhashed. A PoC that drives reuse with a SYN cookie request socket reproduced the crash. The new request socket is unhashed and has a NULL rsk_listener. A lookup that had loaded the address of the old request socket acquired the reference published by tcp_get_cookie_sock() and returned the new object. tcp_v4_rcv() then read sk_state through the NULL listener. The resulting crash was: BUG: kernel NULL pointer dereference, address: 0000000000000012 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page ...

Kernel panic - not syncing: Fatal exception in interrupt After taking a reference, check whether the nulls node is unhashed in both IPv4 and IPv6 established lookups. If it is unhashed or the tuple no longer matches, drop the reference and restart the lookup. Lookups racing with the TIME_WAIT hashdance, or with a request being replaced by its child, now restart and find the new socket instead of returning the old one. Request sockets that were never inserted into ehash can have a nonzero refcount, and a stale lookup can hold a transient reference. Therefore, when SYN cookie, Fast Open, and request migration paths fail after setting a nonzero refcount, release the references held by those paths with reqsk_put() instead of freeing the request directly.

xen-netback: defer xenvif_mcast_addr_list_free()

In the Linux kernel, the following vulnerability has been resolved: xen-netback: defer xenvif_mcast_addr_list_free() In order for the function to legitimately avoid locking/RCU, it needs to run after all TX/RX processing has finished/stopped: Lookups happen from xenvif_start_xmit(), while adds/removes happen from xenvif_tx_action() (called out of xenvif_poll()). Move the call out of xenvif_disconnect_data() (the call to the function from connect()'s error path doesn't require any cleaning up there), and put it past the synchronization point in backend_disconnect(). This is XSA-527 / CVE-2026-100081.

zlib 1.2.11 through 1.3.2 Heap Buffer Overflow via Stale gzwrite Pointer After Failed Write

zlib 1.2.11 through 1.3.2 contains a heap buffer overflow: after an underlying write() fails, gz_write() returns without resetting strm.next_in, leaving it pointed at the caller's buffer. A later gz* write call then derives a position from the stale pointer and writes past a heap allocation; any write() failure reaches it, including EPIPE on a blocking descriptor, and in versions before 1.3.1.2 the failed write must be followed by a gzclearerr() call.

webpack-dev-middleware before 7.4.6 and 8.3.0 Path Traversal via Non-Slash-Terminated publicPath

webpack-dev-middleware 5.3.4, 6.1.2 through 6.1.3, 7.1.0 before 7.4.6, and 8.0.0 before 8.3.0 contains a path traversal vulnerability in getFilenameFromUrl that bypasses the fix for CVE-2024-29180: a publicPath without a trailing slash is matched by string prefix, and the '..' guard runs before that prefix is stripped. Unauthenticated attackers can request a path such as /assets../secret to read files one directory above the output directory when the middleware serves from the physical filesystem through writeToDisk or a custom outputFileSystem.

Dell PowerStore contains an OS Command Injection vulnerability. A high-privileged attacker could exploit this vulnerability, potentially leading to arbitrary root command execution on the appliance.

SQL Injection in Fortinet FortiAnalyzer and FortiManager

A improper neutralization of special elements used in an sql command ('sql injection') vulnerability in Fortinet FortiAnalyzer 8.0.0 through 8.0.1, FortiAnalyzer 7.6.0 through 7.6.7, FortiAnalyzer 7.4.0 through 7.4.11, FortiAnalyzer 7.2.0 through 7.2.12, FortiAnalyzer Cloud 8.0.0 through 8.0.1, FortiAnalyzer Cloud 7.6.0 through 7.6.7, FortiAnalyzer Cloud 7.4.1 through 7.4.11, FortiAnalyzer Cloud 7.2.1 through 7.2.12, FortiManager 8.0.0 through 8.0.1, FortiManager 7.6.0 through 7.6.7, FortiManager 7.4.0 through 7.4.11, FortiManager 7.2.0 through 7.2.12, FortiManager Cloud 8.0.0 through 8.0.1, FortiManager Cloud 7.6.0 through 7.6.7, FortiManager Cloud 7.4.1 through 7.4.11, FortiManager Cloud 7.2.1 through 7.2.12 may allow an authenticated attacker to execute unauthorized SQL commands via specially crafted requests.

Dell PowerStore contains a Server-Side Request Forgery (SSRF) vulnerability. An authenticated user with limited privileges could potentially exploit this vulnerability, potentially leading to information disclosure via requests to internal services.

Oc-mirror: oc-mirror: path traversal / arbitrary file write in operator catalog image extraction

Path traversal / arbitrary file write in oc-mirror's operator catalog image extraction. When mirroring operator catalogs using either the legacy v1 path (--v1) or the OCI feature path (--use-oci-feature), oc-mirror extracts tar entries from catalog image layers without validating that file paths resolve within the intended destination directory.

Rpm: heap-based buffer overflow write in hex2binv() via a mistyped rpmtag_filesignatures header tag

A heap-based buffer overflow flaw was found in rpm. RPMTAG_FILESIGNATURES in a crafted, unsigned RPM package's main header is declared with the wrong header type, causing hex2binv() to allocate a one-byte buffer and then write the tag's attacker-controlled, hex-decoded content — of attacker-chosen length — past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.

Rpm: rpm: integer overflow in iterreadarchivenext() leads to heap-based buffer overflow when parsing untrusted rpm packages

A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an untrusted package.

Krb5: mit krb5 gss-rpc client memory leak on xid mismatch retries

clnttcp_call() in lib/rpc/clnt_tcp.c in MIT Kerberos 5 (aka krb5) does not free the RPC reply verifier between retries, which allows remote attackers to cause a denial of service (memory leak in GSS-RPC client programs) by injecting RPC replies with mismatched XIDs or by triggering authentication retries.

Dell PowerStore contains a use-of-broken-cryptography vulnerability. A low-privileged attacker could exploit it to impersonate another identity, potentially leading to unauthorized access.

Insights-operator: gather serviceaccount has cluster-wide secret read plus nodes/proxy and cluster-reader

The `insights-operator-gather` ClusterRole grants the operator's service account read access to secrets in the core API group with no namespace or resourceNames restriction — therefore, access to every secret in every namespace in the cluster. Ref: https://github.com/openshift/insights-operator/blob/8f15e3157ff09f54ab22801f5b21da35a195cc6d/manifests/03-clusterrole.yaml#L368-L373 ``` - apiGroups: - "" resources: - secrets verbs: - get - list ``` By spawning a pod with the gather service account mounted, an attacker will be able to access any secret in any namespace. ``` spec: serviceAccountName:"gather" ```

Openshift/console: openshift/console: authenticated ssrf via helm chart url fetch

A flaw was found in the OpenShift console. An authenticated console user can exploit a Server-Side Request Forgery (SSRF) vulnerability by providing a specially crafted Helm chart URL without proper validation. This allows the user to make the console pod fetch arbitrary URLs, potentially leading to the disclosure of sensitive information through error messages or enabling blind port scanning within the cluster.

Openshift/oauth-server: openshift/oauth-server: quadratic-time dos via accept-language header underscore bypass on unauthenticated login endpoints

A flaw was found in openshift/oauth-server. The OAuth login and error page endpoints pass the unauthenticated Accept-Language header to golang.org/x/text/language.ParseAcceptLanguage() without input validation. A bypass of the CVE-2022-32149 mitigation exists: the upstream guard counts only '-' characters but the internal BCP 47 scanner aliases '_' to '-' after the guard check. An unauthenticated attacker can send a crafted Accept-Language header using '_' separators to trigger quadratic-time parsing, consuming excessive CPU and denying authentication to all cluster users.

In s_check_valid_tile_param_custom_tile of av1_encoder, there is a possible Non-Heap Buffer Overflow due to a buffer overflow. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation.
