#AMD discloses slew of high severity #security #vulnerabilities for #Zen systems, from the original Zen chips to the latest #Zen4 #CPU, that attacks #BIOS chips, we finally have a #Zenbleed fix. AMD is patching the vulnerabilities through new versions of #AGESA, for #Zen2-based chips, in particular, many of these new AGESAs also patch Zenbleed, including #Epyc #Server chips https://bit.ly/3I1JKds https://www.tomshardware.com/pc-components/cpus/amd-discloses-slew-of-high-severity-security-vulnerabilities-for-zen-chips-that-attack-bios-chips-updates-aim-to-patch-bugs-finally-fix-zenbleed

AMD annuncia nuovi processori per il settore automotive
AMD entra decisamente nel settore automotive con due nuovi processori, il primo per la guida autonoma ed altre attività logiche e il secondo per l'infotainment.

#AMD #Ryzen #Threadripper PRO# 7975WX #CPU Spotted: 32 #Zen4 Cores, 128 MB of L3 cache, and 32 MB of L2 cache. The CPU is expected to feature a TDP of 350W and the base clock speed is reported around 4.0 GHz. And Offer a Huge Performance Jump: 7975WX CPU can be as much as two times faster than its #3970X #Zen2 predecessor and as little as 40% faster

L’attacco Zenbleed consente di rilevare dati sensibili dai processori AMD Zen 2

L’esperto di #sicurezza di #Google Tavis #Ormandy ha identificato una pericolosa #vulnerabilità che interessa i processori #AMD #Zen2.

Il problema consente il #furto di #dati riservati (incluse #password e chiavi di #crittografia) a una velocità di 30 kbps dai core del processore.

#AMD #Zen2 CPUs were found to be vulnerable to a speculative execution bug called #Zenbleed that allows attackers to leak credentials and break encryption.

The good news is that AMD has issued a microcode update, the bad news is that it's only available for their #Epyc 7002 line. The fix for consumer & workstation Ryzen products containing the Zen2 cores will need to wait for a couple months for the fix.

Google Information Security researcher Tavis Ormandy has identified the vulnerability called Zenbleed, present in the entire line of AMD Zen 2 processors, which includes Ryzen 3000, Ryzen 4000, Ryzen 5000, Ryzen 7020, Ryzen Pro 3000 and Ryzen Pro 4000 models.

AMD has released microcode patches to protect Epyc 7002 Rome server chips against the newly discovered Zenbleed vulnerability, but patches for consumer chips with Zen 2 CPU cores won't be ready until later this year. https://www.tomshardware.com/news/zenbleed-bug-allows-data-theft-from-amds-zen-2-processors-patches-released

@taviso Well done with the Zenbleed discovery. It seems that AMD only patched the EPYC processor series. Other Zen2 processors still seems fully vulnerable.

In fact, I think AMD didn't want to announce this early at all. BIOS manufacturers don't even have BIOS firmware updates to protect users. Oops!?
