CVE-2026-64228

The CVE-2026-64228 issue affects the Linux kernel’s ethtool PHY driver: when a PHY driver is unbound via sysfs while the phy_device remains attached, phydev->drv can become NULL, causing ETHTOOL_MSG_PHY_GET to dereference a NULL drv. The root cause is that phy_remove() clears phydev->drv bu...

The vulnerability of the ethtool_get_link_ksettings() function in the net/ethtool/ioctl.c module of the Linux kernel’s networking functions allows a hacker to cause a service failure.

The vulnerability of the ethtoolgetlinkksettings function in the net/ethtool/ioctl.c module of the Linux kernel’s networking functions relates to access to an uninitialized pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

The vulnerability of the eeprom_prepare_data() function in the net/ethtool/eeprom.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the eeprompreparedata function in the net/ethtool/eeprom.c module of the Linux operating system is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected informati...

CVE-2026-63995

A flaw was found in the Linux kernel's ethtool CMIS firmware update code. A malicious module or a corrupted response can provide an oversized payload size during the firmware update process. This can lead to an out-of-bounds write, allowing an attacker to corrupt memory. This memory corruption...

CVE-2026-63996

A flaw was found in the Linux kernel's ethtool CMIS Common Management Interface Specification module. A malicious SFP Small Form-Factor Pluggable module could provide a reply with a length longer than expected, leading to an out-of-bounds write. This vulnerability can result in memory corruption...

CVE-2026-63987

A flaw was found in the Linux kernel's ethtool subsystem. The ethnlupdateprofile function, responsible for updating profile settings, does not properly validate user-controlled input when processing Netlink nest lists. This allows a local attacker to cause an out-of-bounds write, potentially...

CVE-2026-63986

A flaw was found in the Linux kernel's ethtool: tsinfo component. This vulnerability occurs when the ethnltsinfopreparedump function fails to properly initialize a generic netlink message genlmsg but still attempts to cancel it by passing an error pointer. This improper error handling can lead to...

CVE-2026-63985

A flaw was found in the Linux kernel's ethtool component, specifically within the EEPROM Netlink fallback path. The fallbacksetparams function fails to properly validate the length of data being read from the module's EEPROM, allowing for an out-of-bounds read. Additionally, the eepromfallback...

CVE-2026-63998

A flaw was found in the Linux kernel's ethtool module. When attempting to flash transceiver modules' firmware, a validation failure could cause the ethnlopscomplete function to be skipped. This oversight means that an operation initiated by ethnlopsbegin might not be properly concluded, potential...

CVE-2026-63999

A flaw was found in the Linux kernel's ethtool subsystem, specifically within the Receive Side Scaling RSS functionality. The rssprepareget function fails to deallocate memory for the indirection table and hash key buffer if an internal operation ops-getrxfh does not complete successfully. This...
