In the Linux kernel, the following vulnerability has been resolved:
tcp: correct handling of extreme memory squeeze
Testing with iperf3 using the "pasta" protocol splicer has revealed
a problem in the way tcp handles window advertising in extreme memory
squeeze situations.
Under memory pressure, a socket endpoint may temporarily advertise
a zero-sized window, but this is not stored as part of the socket data.
The reasoning behind this is that it is considered a temporary setting
which shouldn't influence any further calculations.
However, if we happen to stall at an unfortunate value of the current
window size, the algorithm selecting a new value will consistently fail
to advertise a non-zero window once we have freed up enough memory.
This means that this side's notion of the current window size is
different from the one last advertised to the peer, causing the latter
to not send any data to resolve the sitution.
The problem occurs on the iperf3 server side, and the socket in question
is a completely regular socket with the default settings for the
fedora40 kernel. We do not use SO_PEEK or SO_RCVBUF on the socket.
The following excerpt of a logging session, with own comments added,
shows more in detail what is happening:

CVE-2024-57953 [MEDIUM] Linux kernel (HWE) vulnerabilities
Title: Linux kernel (HWE) vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the CIFS network file system implementation in the
Linux kernel did not properly verify the target namespace when handling
upcalls. An attacker could use this to expose sensitive information.
(CVE-2025-2312)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.

kernel: tcp: correct handling of extreme memory squeeze
vendor_redhat·2025-02-27·CVSS 5.5
CVE-2025-21710 [MEDIUM] CWE-200 kernel: tcp: correct handling of extreme memory squeeze
kernel: tcp: correct handling of extreme memory squeeze
In the Linux kernel, the following vulnerability has been resolved:
tcp: correct handling of extreme memory squeeze
Testing with iperf3 using the "pasta" protocol splicer has revealed
a problem in the way tcp handles window advertising in extreme memory
squeeze situations.
Under memory pressure, a socket endpoint may temporarily advertise
a zero-sized window, but this is not stored as part of the socket data.
The reasoning behind this is that it is considered a temporary setting
which shouldn't influence any further calculations.
However, if we happen to stall at an unfortunate value of the current
window size, the algorithm selecting a new value will consistently fail
to advertise a non-zero window once we have freed up enough memor
