Yo, fellow Linuxers, #CVE20256019 has been published and updates are available. The TL;DR. A Local Privilege Escalation to root via libblockdev. Notice the local. So you need to be able to be on the machine. Still, update now.

Dear @Gargron — Can we take another, fresh look at https://github.com/mastodon/mastodon/issues/20694 ? Hashtags should ultimately support full UTF8, IMHO, but adding at the very least the dash would be very helpful. It's not just band or artist names. CVEs are a better example. It would be really helpful when I can use #CVE-2025-6019 instead of #CVE20256019 or #CVE_2025_6019 as I am forced to do now. I guess hashtags are not in scope of the ActivityPub protocol, @evan ?

@jwildeboer @Gargron @evan Is #cve_2025_6019 an option for you?

(Edit: had to remove the / variant, #Mastodon doesn't do nested-obsidian-style variants either :)

@mina Sure. But it doesn't explain why the dash is not allowed. my example is an official CVE. Which is CVE-YEAR-Number, example: CVE-2025-6019. It is NOT CVE_2025_6019. So why is underscore allowed in a hashtag but the dash isn't? @Gargron @evan

Citrix has fixed a critical vulnerability (CVE-2025-5777) in NetScaler ADC and NetScaler Gateway, similar to CitrixBleed. The vulnerability allows unauthorized attackers to access session tokens from internet-facing devices, potentially gaining access to the appliances. Customers are urged to upgrade to the latest versions and terminate active sessions to mitigate the risk.

#Citrix Critical Netscaler #vulnerability CVE-2025-5777 patch released!
Like CtirixBleed this vulnerability allows attackers to grab valid session tokens from the memory of internet-facing #Netscaler devices by sending malformed request:

It's 2025. We can use emojis in hashtags in some apps. But we still cannot use "-". So, no. still no #CVE-2025-0619. Will this ever be possible? Le sigh.

Canadian Telco not patching year old RCE 🙄

“The Canadian Centre for Cyber Security and the FBI confirm that the Chinese state-sponsored 'Salt Typhoon' hacking group is also targeting Canadian telecommunication firms, breaching a telecom provider in February.

During the February 2025 incident, Salt Typhoon exploited the CVE-2023-20198 flaw, a critical Cisco IOS XE vulnerability allowing remote, unauthenticated attackers to create arbitrary accounts and gain admin-level privileges.”
