Smashing Security podcast #294: The Virgin trains swindler, cyber clowns, and AirTag election debacle

Read Time:23 Second

Someone’s election-fiddling is uncovered with an Apple AirTag, a cyber scandal rocks Germany, and a swindler steals a fortune due to trains being delayed.

All this and much more is discussed in the latest edition of the award-winning “Smashing Security” podcast by computer security veterans Graham Cluley and Carole Theriault, joined this week by runZero’s Chris Kirsch.

Plus don’t miss our featured interview with Akamai’s Patrick Sullivan talking about bots in the retail sector.

USN-5693-1: Linux kernel (OEM) vulnerabilities

Read Time:2 Minute, 11 Second

David Bouman and Billy Jheng Bing Jhong discovered that a race condition
existed in the io_uring subsystem in the Linux kernel, leading to a use-
after-free vulnerability. A local attacker could use this to cause a denial
of service (system crash) or possibly execute arbitrary code.
(CVE-2022-2602)

Duoming Zhou discovered that race conditions existed in the timer handling
implementation of the Linux kernel’s Rose X.25 protocol layer, resulting in
use-after-free vulnerabilities. A local attacker could use this to cause a
denial of service (system crash). (CVE-2022-2318)

Hao Sun and Jiacheng Xu discovered that the NILFS file system
implementation in the Linux kernel contained a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-2978)

Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in
the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly expose sensitive information (kernel
memory). (CVE-2022-3028)

Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX
storage controller driver in the Linux kernel did not properly handle
certain structures. A local attacker could potentially use this to expose
sensitive information (kernel memory). (CVE-2022-40768)

Sönke Huster discovered that an integer overflow vulnerability existed in
the WiFi driver stack in the Linux kernel, leading to a buffer overflow. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-41674)

Sönke Huster discovered that a use-after-free vulnerability existed in the
WiFi driver stack in the Linux kernel. A physically proximate attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-42719)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly perform reference counting in some situations, leading to a
use-after-free vulnerability. A physically proximate attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2022-42720)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel did
not properly handle BSSID/SSID lists in some situations. A physically
proximate attacker could use this to cause a denial of service (infinite
loop). (CVE-2022-42721)

Sönke Huster discovered that the WiFi driver stack in the Linux kernel
contained a NULL pointer dereference vulnerability in certain situations. A
physically proximate attacker could use this to cause a denial of service
(system crash). (CVE-2022-42722)
