In the Linux kernel, the following vulnerability has been resolved:

net: ch9200: fix uninitialised access during mii_nway_restart

In mii_nway_restart() the code attempts to call mii->mdio_read which is ch9200_mdio_read(). ch9200_mdio_read() utilises a local buffer called "buff", which is initialised with control_read(). However "buff" is conditionally initialised inside control_read():

if (err == size) { memcpy(data, buf, size); }

If the condition of "err == size" is not met, then "buff" remains uninitialised. Once this happens the uninitialised "buff" is accessed and returned during ch9200_mdio_read():

return (buff[0] | buff[1] << 8);

The problem stems from the fact that ch9200_mdio_read() ignores the return value of control_read(), leading to uinit-access of "buff".

To fix this we should check the return value of control_read() and return early on error.

ICSA-26-043-06 — Siemens SINEC OS

There is a stack overflow vulnerability in ash.c:6030 in busybox before 1.35. In the environment of Internet of Vehicles, this vulnerability can be executed from command to arbitrary code execution. In affected libpcap versions during the setup of a remote packet capture the internal function sock_initaddress() calls getaddrinfo() and possibly freeaddrinfo(), but does not clearly indicate to the caller function whether freeaddrinfo() still remains to be called after the function returns. This makes it possible in some scenarios that both the function and its caller call freeaddrinfo() for the same allocated memory block. A similar problem was reported in Apple libpcap, to which Apple assigned CVE-2023-40400. An issue in the CPIO command of Busybox v1.33.2 allows attackers to execute a directory traversal. A use-after-free vulnerability was discovered in xasprintf function in xfuncs_printf.c:344 in BusyBox v.1.36.1. A use-after-free vulnerability in BusyBox v.1.36.1 allows attackers to cause a denial of service via a crafted awk pattern in the awk.c evaluate function. A use-after-free vulnerability was discovered in BusyBox v.1.36.1 via a crafted awk pattern in the awk.c copyvar function. A heap-buffer-overflow was discovered in BusyBox v.1.36.1 in the next_token function at awk.c:1159. libcurl's ASN1 parser has this utf8asn1str() function used for parsing an ASN.1 UTF-8 string. Itcan detect an invalid field and return error. Unfortunately, when doing so it also invokes `fr…

OESA-2025-2080 — kernel security update

Affected: openEuler:20.03-LTS-SP4: kernel

The Linux Kernel, the operating system core itself. Security Fix(es):

A vulnerability was found in Linux Kernel up to 6.15.3 (Operating System). It has been rated as problematic.Using CWE to declare the problem leads to CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions.Impacted is confidentiality, integrity, and availability.Upgrading to version 5.4.295, 5.10.239, 5.15.186, 6.1.142, 6.6.95, 6.12.35, 6.15.4 or 6.16-rc1 eliminates this vulnerability. Applying the patch 119766de4930ff40db9f36b960cb53b0c400e81b/33163c68d2e3061fa3935b5f0a1867958b1cdbd2/9da3e442714f7f4393ff01c265c4959c03e88c2f/9a350f30d65197354706b7759b5c89d6c267b1a9/6bd2569d0b2f918e9581f744df0263caf73ee76c/4da7fcc098218ff92b2e83a43f545c02f714cedd/cdaa6d1cb2ff1219c6c822b27655dd170ffb0f72/9ad0452c0277b816a435433cca601304cfac7c21 is able to eliminate this problem. The bugfix is ready for download at git.kernel.org. The best possible mitigation is suggested to be upgrading to the latest version.The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-19447).(CVE-2025-38086)

In the Linux kernel, the following vulnerability has been resolved:

sch_hfsc: make hfsc_qlen_notify() idempotent

hfsc_qlen_notify() is not idempotent either and not friendly to its callers, like fq_codel_dequeue(). Let's make it idempotent to ease qdisc_tree_reduce_backlog() callers' life:
