CVE-2026-64120

In the Linux kernel, the following vulnerability has been resolved: net: ethtool: fix NULL pointer dereference in phyreplysize In phypreparedata, several strings such as 'name', 'drvname', 'upstreamsfpname', and 'downstreamsfpname' are allocated using kstrdup. However, these allocations were not...

In the Linux kernel, the following vulnerability has been resolved: net: ethtool: fix NULL pointer dereference in phyreplysize In phypreparedata, several strings such as 'name', 'drvname', 'upstreamsfpname', and 'downstreamsfpname' are allocated using kstrdup. However, these allocations were not...

CVE-2026-64120

CVE-2026-64120 pertains to the Linux kernel’s phy_prepare_data() in the net: ethtool path. The issue arises from kstrdup() allocations for strings (name, drvname, upstream_sfp_name, downstream_sfp_name) that were not NULL-checked, allowing a NULL dereference in phy_reply_size() when strlen() is c...

CVE-2026-63932

In the Linux kernel IIO chemical mhz19b driver, mhz19b_receive_buf() appends serdev chunks into a fixed MHZ19B_CMD_SIZE buffer and advances buf_idx without ensuring fit, enabling a potential overflow of st->buf from a large callback. The patch resets the reply state before each command and rej...

Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-001787)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001787 advisory. The nfs4getacluncached function in fs/nfs/nfs4proc.c in the NFSv4 implementation in the Linux kernel before 3.3.2 uses an incorrect length variable during a copy...

The vulnerability of the strset_reply_size() function in the net/ethtool/strset.c module, which is part of the Linux kernel’s networking functions, allows a hacker to cause a service failure.

The vulnerability of the strsetreplysize function in the net/ethtool/strset.c module of the Linux kernel’s networking functions is related to access control deficiencies. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...

SUSE CVE-2025-37791

In the Linux kernel, the following vulnerability has been resolved: ethtool: cmiscdb: use correct rpl size in ethtoolcmismodulepoll rpl is passed as a pointer to ethtoolcmismodulepoll, so the correct size of rpl is sizeofrpl which should be just 1 byte. Using the pointer size instead can cause...
